The act of taking a poo across someones eyes when they are passed out so when they wake up they try to get whatever it is off their eyes and just smear it everywhere so they cant see.
Me and Cody got so fucked last night, and when we woke up we had mexican blindfolds on.

A term which has strange sexual connotation but no real definition. It was created out of a drunken stupor and suggest truly revolting things. An interesting threat or insult to use on people who can't figure out what the hell it means.
