Racktive 

When a girl is racktive she is usually quite skinny, plain-looking and dull but has disproportionately large pillow-like natural breasts due to which every guy wants to bone her. In other words, she is solely recognized for her prominent tits because of which guys find her (rack) attractive!

Tony: Hey Tim have you seen the jugs on that chick

Tim: Shit man she looks like a freakin' stick with a pair of baloons .
Tony: She's one racktive piece of meat bro, I wanna hump her so bad !
Tim: Aw hellz no! Imma tittyfuck her first nigga !
