Backpack 

A contributing factor to the growth of back pains. To help with the stress of all students this was invented to give teachers the excuse to load you with every book they want. Weight limits should be an obtainable thing.

Are you going on a vacation? Or to study?

A backpack should be and item to carry when camping.

I just met this guy, he was super aggressive...a total backpack.

Backpack Learner

A student who attends the beginning of class, but regularly takes off to "the bathroom" for ten-twenty minutes at a time, as if the backpack is going to do all the learning for him/her.

I always email my instructor at the last second to ask the most basic question because I'm a clueless backpack learner.

backpack rule 

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!"

Backpack-slap 

When a person puts backpack on and intentionally hits someone else in the face so hard the person becomes hurt.
