sweat under one's breasts (sweat + boob = swoob)
The combination of the hot day and the tight sports bra created a serious swoob problem for Alicia.
When it is knarly hot and you have a profuse sweat going onunder your breasts.
Sweaty + Boobs= Swoobs
I have a serious case of the swoobs.
When boobs get sweaty, underneath and/or in between.
Guy: Oh man, its hot out today. I got swalls over here.
Girl: I hear ya, I got some swoobs
When sweat gathers in your cleavage...you get swoobs
Man, that girl has got some swoobs.
when a female sweats in her boob when shes exercising or hot
omg, all this running is making me swoob.
Them damn sweaty boobs is what swoobs means. Like when girl comes up to you with a nice bust but they are all sweaty and wet and the rest of her isn't sweaty, that's swoobs.
Wow! Did you see that babe that had those gross ass swoobs?
