cock stopper

A valve used in chemistry for titrations that controls the flow of a liquid (preferably white). They are prone to leakage and can cause a large, white mess. Cock stoppers are sometimes refereed to as "cocks" for short.

Dude did you see his 'cock was leaking? That will make a mess! Those cock stoppers are so gay!
