A swb (pronounced swib) is a straight white boy. These are not your average straight white boys, though. Oh, no! Swbs are those douchey straight guys who rub you the wrong way if you catch my drift. They strut around in packs, lurking for the V (and by V, I mean vagina). In short, they are fuckboys.
Swb: Hey baby, wanna fuck?
Girl: Eeeeeeeeewwwwwwwww, gross! Get away from me, you swb! You nasty!

Swb: Dude, you bang her?
Classy man: Uh, no. We went to the zoo and fed the goats.
Swb: So...you touched her butt?
Classy man: Unbelievable. What a swb!

Stupid White Bitch, more effective than skinny white bitch, used to refer to a dumb, usually Caucasian female who is a complete idiot, although it may be used to refer to anyone who thinks they are smart but are actually really fucking stupid. Can be used after some one tries to sound smart and fails miserably.
Irvis, you are such a swb.

swb is an abreaviation for “since way back”. This can be used in text, as a contact name.
An example would be if you were greeting a friend to a friend and you wanted them to know you’ve known this person a while.

“Aye my G, this the mandem I’ve been talkin’ ‘bout. I know him ‘since way back’.”

This could also be a contact name for someone “swb”

SWB's have no butt. It is too slim to hold up pants worn below the waist but belted in the middle of the butt.

SWB's ass is not the correct shape needed to hold up their jeans and show their boxers at the same time.

My pants kept falling down when I try to look like Lil Wayne or any rapper these days. I do not know how they keep their pants from falling down.

I finally did ask someone how to get your pants to hold on to your azz and still show your boxers. Its a secret....One SWB's need.

Sister with benefits; someone who is closer than a best friend (no romantic connotation) that you screw around with. The other side of the equation is the bwb (brother with benefits).
My swb(Sister with benefits) gave me the best blowjob ever last night.
