After masturbation when semen starts to thicken and dry in the head of a mans penis, and he attempts to urinate and is surprised by an uncontrollable stream of piss.
So I whacked off in the shower, and when I got out and went to take a piss, I accidentally pissed on my foot due to a cum-clog.
A person who takes a long time to ejaculate or cannot help others to do so.
I tried to sex it up last night, but my boyfriend was being a cumclogger.
Bobba was about to cum, but then he remembered sex was a sin, that foolish cumclogger!
Julian was ejaculating last night when suddenly he forgot to take off the ejaculation from the tip of his penis but CumClogger™ came and saved the day and removed the ejaculation from his penis to prevent it from getting dry.
