back-stap

When you staple a paper or anything else for that matter but you do it backwards so that the sharp ends are facing you.

The stapler is facing the opposite way.

back up girl

shes the type of girl thats ok with being second best. or in my eyes the first place loser.

she waits around until you a your bf broke and takes the sloppy seconds.

more than likely has brown hair, chubby, and brown eyes.


she usually still keeps talking to your bf when you dont now it, because shes trying to get with him.


if you have a sleeze of a bf then he'll probably cheat on you with her.

2/3 of the time its a past ex, who wants another go.

you better watch out, your boy has all the symptoms of having a back up girl.

back alley

a bar in downtown fullerton california where fashion-tattood douchebags in girls pants go to socialize with each other whilst drinking overpriced booze served in warm glasses.

wanna go to the back alley? no thanks, i'd rather go to a bar with good service at decent prices and avoid all the douchebaggery.
