An acronym for the commonly used phrase "Gets Me Every Time," referring to something that no matter how many times you see it it always makes you laugh.

Pronunciation: Spelling the acronym out is more clear to those not in the know, however it is more fun to say "guh-met".
Guy Buddy 1: Did you get the video Jerry forwarded around?

Guy Buddy 1: Yeah that's the one.
Guy Buddy 2: Totally bro. Totes GMET.
