The act of ejaculating into the foreskin whilst holding it closed with ones fingers. It is a common practice for horny teens who are unable to predict when they may have the urges to masturbate in bed. It allows the young man to sneak to the bathroom without any splash on the sheets.
I was so horny last night that I had no time to prepare. My only option was to pinch the tip.

Get the Pinch the tip mug.
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!
