To 'alligate' is to have a photo taken of you with any object covering the bottom half of your face i.e. directly below
the eyes. You can use bar
menu's, statues, people, buildings or any manner of objects; the
possibilities are endless.

Tom: "Holy shit look at that statue! Shall we do some
alligating on it?"
Lennie "Yeh,
