A word used to rip on any person who has annoyed you, pissed you off, ect. Technically a barista (from the Italian for "bartender") is a person who is coffee-house employee, but in the vulgar world we live in these days anybody can be called a "shitty barista" for no apparent reason in most cases. This word is from the movie Zack and Miri Make a Porno

when you've done something so cringe you can't stop replaying it in your head and it stops you from getting on with your every day life
