an affliction that occurs when one becomes so drunk that one eye closes half way while the other remains open. This usually occurs near the end of the night, just before passing out.
A: ZOMG, Joe is puking everywhere!
B: Yeah, I knew he was shwasted. He had the big eye at nine o'clock
Joe: Bllaaah Blaahhhh, Oh man I can't stop puking everywhere
