A game, usually played while drinking, where you put a lemon slice in your mouth and suck on it as long as possible. Unlike in the game of life, the person who sucks the longest wins.

First seen in the "Prince" episode of New Girl.
"Surrounded by celebrities and millionaires, and you dingbats are playing lemon mouth. Rind me, woman." -Schmidt

Get the lemon mouth mug.
When you have sex with someone's mouth, put some tuna in there to get it to smell like a proper pussy and squirt in a bit of lemon to get them to pucker up nice and tight.
Pegwole is one sweet lemon tuna mouth, that he is.
