1) swear to fucking God. When a person has had either enough of what you have said or it's so funny that they can't put it in words.
2) shot the fucking goat. Do t know how to describe this one. I guess its exactly as it sounds. Usually will here this from your cousin John that lives on the pasture with the rest of the farm hands.

Girl: Hey I (1) stfg. You better not have done it.
Guy: what I just (2) stfg.
Girl: that was my vegan cousin John. I'm calling the cops!
Guy: Crap that's sad. Alexa play Despacito.

STFG stands for Super Teacher Friends Group. This is a group of teachers that are more than friends. They are there for each other on the good days and the bad days. They are such great teachers and friends!

The students were so crazy today! Must be a full moon. Going to get drinks with my STFG tonight.
