A situation similiar to
blueballs in which a man is on the very tip of
ejaculating when his
ho totally ditches him or does something to stop him from shooting his wad, jamming his
cock with
semen in the process. Also can make urinating quite difficult afterwards.
AKA the very worse weapon the
cocktease has in it's arsenal. The ultimate bait and switch.
Dave: "Man, I was totally getting a handjob from Jenny but that bitch totally
cockjammed me by saying she had work in the morning and telling me to rub one out on my own."
Phil: "That sucks
bro. What a fucking
Cockjammer. Well at least you almost busted a nut."
Dave: "Bust a nut?!?! She almost busted MY FUCKING DICK!! It hurts when I touch it. I think my penis knew she abandoned it before the deed was done. It's extremely angry about the whole ordeal. Oh, and the best thing was I couldn't
piss for 4 hours either."
