Right before a man is about to ejaculate, he (or someone else)
pinches the tip of his penis to stop the flow of
the goods. Pressure builds, and right before his eyes are about to
pop out he (or someone else) releases the shot which now has an extremely extended range of distance.
Jon: Dude, Jake!
What the fuck is that hanging down from your ceiling above your bed?!
Jake: Awww shit, forget to clean up last night after trying to make some
knuckle babies.
Jon: How the fuck did you
get it up there?!
Jake: That's easy DUDE! Just pinch the tip, then let 'er rip!
