Shakespeare invented more words than most people even know. Seriously, there's at least 1,500 different words and phrases that don't appear anywhere prior to the Bard of Avon putting them on paper. When he got stuck trying to think up a word, the man just made his own.
It's kind of like what rappers do today, except the words Shakespeare made up got embedded into our culture and have formed the cornerstone of our discourse, rather than being obnoxiously spouted by white college students trying to be ironic. And while they weren't all winners ("unhair" still seems to be struggling) others, as you'll see, are so common you've probably already quoted Shakespeare today and you didn't even know it. Fo' sheezy.
A Midsummer Night's Dream, Act III, Scene ii, Oberon to Puck.
"Then crush this herb into Lysander's eye;
Whose liquor hath this virtuous property,
To take from thence all error with his might,
And make his eyeballs roll with wonted sight."
"Grind leaves and shit into that guy's eyes until he goes blind."
Where We'd Be Without It:
Totally unable to explain where we sniped this guy in Call of Duty 4.
Why It's Un-Fucking-Believable:
Yep, as far as we know that's the first time anybody wrote the word "eyeballs." "Eyes" were there, "balls" were there, yet no one until Billy thought to put the two together. Well, there was one guy, but according to historical records that ended in an arrest for assault and indecent exposure.
