Backpack boys

Backpack boys are a group of pubescent wannabe hype beasts. They wear large backpacks that are much too large for their teenage bodies. They travel in packs, and all mysteriously look alike, but they are NOT related. They never seem to talk, just walk around with their big backpacks. The term “backpack boys” was coined by Daisy Baierl in 2019.

nobody: “I’m going to go sit with the back boys”

Nobody: “The backpack boys are hot”

Backpack College

A backpack college is when a student comes home from college every weekendvinstead of staying and partying at your school. This is often confused with a suitcase college which really means a commuter college and the student has no choice but to go home.

Tim-Where is everyone at?
Bill- People are bitches and go home every weekend.
Tim- This is such a backpack college!
