When the smaller mate (regardless of sex (if female use stap-on similar to pegging)) rides on the back on the bigger one (who runs as fast as they can) while fucking them in the ass.
Guy 1: Yo last night my girl gave me the Alabama Backpack
Guy 2: Nice! How far did you run?
Guy 1: All the way to the gas station!
Guy2 : Damn!!

It's getting harder and harder these days to determine whether or not a girl is old enough to be checking out. Girls from ages 15-21 can all look the same these days. If a girl is wearing a backpack(like a hello kitty one), chances are she's too young and you should look away before being called out for being a creeper. If she has no backpack than it's safe to look, but still be cautious if you choose to engage in conversation.
Benji- "That girl is cute but she looks like she might be young."
Joe- "Gotta use the backpack rule."
Benji -"What's the backpack rule?"
Joe- "If she's wearing a backpack she's too young."
*Hot girl walks in*
Joe- "See man, no backpack... she's fair game!"
Joe- "Gotta use the backpack rule."
Benji -"What's the backpack rule?"
Joe- "If she's wearing a backpack she's too young."

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.

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!
