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."
A person whom cannot be without a penis in their life. A cock jumper always has a boyfriend until they find the next one. A cock jumper is never alone.
That damn Sam is such a cock jumper she jumped off Eddie for Fred in less than 24 hours.
Nickname given to bales of marijuana thrown overboard or out of airplanes. Origin is reportedly from members of the US Coast Guard in the area of Southern Florida.
