A fun trick to play on an female during intercourse. The male gets the female to go on her hands and knees and then he comes up behind her and right when she leasts expects it, he grabs her arms and pushes her around the room on her face.
God damn, last night the bitch wouldn't cook me dinner, so when we were about to fuck, i gave her the ol' vaccum cleaner!
to express the nothingness left on the area of the marsbar once a bite has been taken. also a piece of marsbar which has been broken into 2 seperate pieces to be shared with one piece significantly smaller than the other, thus being a vaccum marsbar
happycamper - "wanta piece of this marsbar?"
CBlast - "woah check out the vaccum in the side of this marsbar"
