Sarcasm, a form of humor concerning misleading sentences, but said in a mocking tone. Clearly explaining you don't mean what you said. It's use is mainly for pointing out stupid remarks/questions/statements.
Dry sarcasm, is the type of sarcasm no one enjoys. The type you can't detect. Which is friggin' misleading.
Bob - Hey is the party at Cathy's?
Steve- Oh, yeeah.
Bob - Okay, because i thought it was at John's.
Steve - Wow you're retarded. It is at John's.
Bob - But you said...
Steve - Oh yeah sure, that's exactly what I said.
Bob - Screw you, Steve.
If you can't understand where the sarcasm is. I have proven my point.
The exact opposite, if you don't see you're being ridiculed at this point, you are retarded.
Steve - Hey, I'm pretty tired. I'm going to bed.
Bob - WELL DUUUUH! WHERE ELSE WOULD SLEEP WHEN YOU'RE TIRED? THE MOON?

Bob - Oh man no! It was Sooooooooo boring! Jeez what else!?
Steve then shoots Bob in the head.
Steve - People like this can't live.
Judge - You have been charged with murder.
