The 9 Most Devastating Insults From Around the World

doesn't look like either of them own it i mean.....em...

nah don't know about the irish one, I never heard it before, i never even heard the word "Walt".
Is there a third person involved with the two grandads? that hand doesn't look like either of the two men you can see

Lovely, this comment system that doesn't allow profanities!
Just to make sure; the translation is: Jump into your own a-hole. That's ass + hole, and for Zarquan's sake don't edit all the "holes" out

My dear crack heads, in addition to misspelling the Icelandic profanities quite badly (for which you are forgiven) you miss out on the most graphic and biological one (which is unforgivable).

If you ever come and visit us (it's cheap now that our local Króna is worth one tenth of monkey s**t), try walking up to a random old lady and say "Hoppaðu upp í rassgatið á þér!" to her. It is pronounced something like "hop'athu up ee rasgatith au thjer", with all u's like in "under" and all i's like in "in".
The meaning is some thing like "Jump up into your own a*****e" and unlike the insults above (some of which are simply translated from English) it has been around for a while. But trust me, this works. Old ladies will faint, sailors will kick the snot out of you.

oh man those 2 old men making out is NASTY i feel sick

Theres another armenian swear which means: "im going to s**t in your mouth 3 times"

Cuz, i know, 4 times and u actually start to like it

"Brazo de santo" (saints arm) it means no great deal in Spain, but if you say it in Mexico, yes, you're talking about an erection. Still, it doesn't have anything to do with holy people, but the famous-silver-masked-mexican-wrestling-legend "El Santo" (The Saint). The saying goes like "Me pongo duro como el brazo de El Santo", (translated: I get as hard as El Santo's arm) which means a really hard-on.
Regarding mexican insults, we have a strong fixation on our (holy) mother's image so anything that mentions any action against our mommas will be considered as a death-serious insult.
Please note that if you say anything against the father's image, most of us will totally agree with you...
Insult: "Tu padre se la come!", translated, your father eats it all!
Retort: (scratching the temples) well... yeah, sometimes. Specially when he's drunk...

Replace the word father for mother, and before you reach the next "s" you'll have anyone of us right on your throat with a machete/knife/gun/broken-tequila-bottle asking in a very violent and polite way to take it back.
Most common insult in Mexico: "Chinga tu re-puta madre!" (f***/annoy/molest/importunate/screw/upset/etc. your top-whore mother)

Another Serbian one (I think it beats all the rest): May a horse with a bloody dick f**k your sister on your mother's grave looking at death in the eyes!!! (da bog da ti kon s'krvavim kurcem jebao sestru na majchinom grobu ochi u ochi sa smrchu!!!)
There is also a "cute" Macedonian one (originating in the town of Bitola): "May I steer your stew with my dick!!!" (Da ti mesham v'mandja so kurov!!!)

was the grandfatherfucker picture really necessary?

I'm a Spanish speaker and I'm afraid I have never heard such an insult (suck butter from my ass!!) either in Spain or South America. I don't know where you guys got it from. However, the insults you mention below do exist and they're fairly common, indeed.

I should save these and say, "Yes?" at the end of them and see if they say "maybe"! Exaple: "May an long day cham mui, yes?" (You eat pubic hair with salt dip, yes?)

I only have two grandfathers. I'm not sure how the Arabs got "seventh grandfather". Unless they mean seven grandfathers back -- my great-great-great-great-great-great-grandfather. I have 128 of those.

does anyone feel like just using these on random passerbys or close friends for no apparent reason. solely to derive a reaction and bring new phrases to ur area

from Iceland they forgot about hommatittur: gay f****r and Fjandinn hafi þig: the devil may have your soul!

HAHAHA!!! this is awesome

Let the rats ejaculate on you, indeed!

I am spaniard and I've never listened about the butter insults.
In my homeregion in the north of Spain, Asturias we have the supreme insult, it is not spanish but Asturian our own language and says: "Cago en el ratu puerco la tu puta madre", that could be translated as "I s**t on the dirty rat of your whore mother", "rat" refering to... well, you get it.
Other insults I like in Spanish are:
"Sodomizaré tu cadaver" - "I will sodomize your dead body"
"Te voy a arrancar la cabeza y follar por la traquea" - "I am going to rip you head off and f**k you by the trachea"

who ever wrote this he is not from serbia...if u want to fix this "May God give you to search for your children with a Geiger counter" (Da bog da tražio decu Gajgerovim brojačem)....this is correct...change it

Well am Kuwaity ( which makes me Arab) and i never heard of these insults lol
here are some of the really common insults:
"Kes omik " which means ur mothers vagina"
"weld elgahba" = son of a b***h

here in argentina we also use a lot of s**t when cursing. for example, anda a cagar (go s**t, i know it doesnt sound well but it will be like a go f**k yourself), puto de mierda (it it translates shitfagg, it would mean f*****g f*g). theres a lot more, im proud of our insults.

Following our fixation with s**t, here in Spain, we also use "me cago en la mar" (i s**t in the sea)or the generic "Me cago en todo" (i s**t on everything). Altough a more bizzar (not a very bad insult) is "que te zurzan" which is the equivalent of screw you but direcly translates to "get darned"
