What you get when you don't piss for a while after sex. Sometimes results in a little bleeding.
Damn, I fucked this skanky ho and a few hours later I tried to piss, but I had painful cum clots that hurt like a bastard.

The act of cumming without the cum.

When one's cum is clogged in the shaft of the penis causing a very painful ejaculation in dribbles.
