A word used in place of 'fuck you'. Word must be said in complete silence...for added emphasis. Works best with women and wet t-shirts.
"I wanna vacuum" could mean "I wanna fuck you" if the words were mouthed and no sound is present.

A vacuum is when a girl is giving you a blowjob and right before you cum you pull her head off your dick and turn her head sideways and cum in her ear and perform a Q-tip. Then you suck the cum out of her ear and spit it in her eyes.
Last night i gave the hooker a Q-tip and she didn't like it so i gave her a vacuum.
