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.

when you take two different types of biscuit, one that's new and one that you know you like, just in case you don't like the new biscuit.
