Side-chick 

A dusty, thirsty bird that one keeps around strictly for beating up the hot box. You usually have to gas her up by alluding to the possibility of a relationship in the near future, in order to get the buns. A throw away broad that an individual wears out like a boss, unbeknownst to said individual's main squeeze. Side-chicks are usually cool with their status as a slide-off due to the fact that they either have no shame or they're blinded by love. Not someone that you'd want to bone without a rubber. Guys can be side-chicks as well which could be equally, if not even more pathetic.

My wife is headed to work so I'm just going to sleep until two in the afternoon and then call the side-chick over real quick to get my dick wet for a minute.

Like the word "sidekick" to a superhero, a side chick is a girl that tags along with another more popular girl or guy.

Brittany's side-chick is sooo lame.

Side chick 

The kind of girls without a boyfriend who are often "the third wheel" in a relationship setting.
Usually these girls want to be with the guy whom they're associated with, but there was no agreement for them to go that step further.

The man whom the side chick is associated with is pretty indecisive about whom they want romantic relations with, but since they got hung up on several chicks, he might as well have his side chicks.

Julia isn't Jason's girlfriend. And Meghan isn't his girlfriend either. Apparently, they're his side chicks. Jason won't decide!

Side Chick 

The girl a guy cheats on his girlfriend with because she's better in bed. Not always a bad thing to the girl and guy, just society.

I'm flattered to be the side chick because it means I'm better in bed than his lousy girlfriend is.
