A side chick is a women/thot/hoe
that is dating a man that has a girlfriend and the side chick knows he has a girlfriend. Usually a side chick is used for off and on sex while the girlfriend is not with the man. A man can have many side chicks just to f*ck.
Man: Hey babe when you go Hawaii with your family I’ll Be with my side chick so I can get my daily blow jobs, is that fine?
Woman: Oh okay but I suck better!
Man: yeah but not so good at anal
Hahahahaha!
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 afternoonand then call the side-chick over real quick to get my dick wet for a minute.
