Noun, verb; A sexual position featuring a woman laying on her back while a man has sex with her breasts. However, he is doing so while kneeling above the woman and facing her feet (see also: reverse titty-fuck). If done correctly, this should lead to the mans scrotum swinging violently into the chin or face of the aforementioned woman. Thus creating an effect similar to that of a wrecking-ball.
dude, i wrecking-balled that girl so hard last night that her silicone bags burst.
