When you are banging a girl/guy and right before you blow you pull out and jizz into his/her bellybutton and then take one of fingers on your RIGHT hand and push it in and out of their bellybutton so it makes a noise.
I was banging that chick so hard last night and right before i blew my load in her I pulled out and gave her the old, grease hole and she loved it!
A subspecies of gasshole. A greasehole is a person that exhibits many similar qualities of a gasshole, those being burping and farting considerably more than average, with the added bonus of just being a greasy fuck. Will often have greasy hair & oily skin, eat only greasy food, grease stained clothing and/or all of the above.
Mitch: "I gotta stop eating so much fast food. I'm sweating in places I really shouldn't be sweating in."
Ricky: "You're such a fucking greasehole."
n. software that is no longer sold or supported by the original publisher / developer, often found as free downloads on the internet because it cannot be obtained elsewhere. Not legal, but often seen as morally acceptable because the company that made it is no longer selling the title, nor releasing it as freeware, therefore abandonware is "keeping the gamealive", so to speak.
Doom II is not abandonware because idstill sells it, while The Incredible Machine is not sold, therefore is abandonware.
