Taking a piss without bothering to zip up your pants.

Unquestionably the zipless piss is the truest identifying hallmark of an alcoholic.

zipless fuck 

A usually spontaneous sexual encounter between strangers with little or no personal information exchanged. The highest plateau of casual sex.

Walking into an elevator, locking eyes with a woman (or man) and without further ado proceedeing to engage in hot, passionate sex between the 5th and 45th floors. You finish, compose yourselves, and go your seperate ways, never to meet again.

zipless fuck 

A phrase coined by Erica Jong in the book "Fear of Flying". As described by her - It is a sexual encounter between strangers that has the swift compression of a dream and is seemingly free of all remorse and guilt. It is absolutely pure, there is no power game and it is free of ulterior motives. It has also been described as the perfect one night stand.

The zipless fuck is the purest thing there is, rarer than the unicorn and I have never had one. - "Fear of Flying"
