A type of interdimensional entity which uses it's extremely powerful sense of smell to locate human testicles which have accumulated large reserves of semen due to long periods of non-ejaculation, which it relies on as its primary food source. This is also thought to be the reason for the occurence of most wet dreams, which are believed to be the result of stimulation of the penis by the monster in order to acquire semen. This is difficult to prove however, as the monster itself is rarely seen as it avoids detection by humans at all costs and will retreat into it's own dimension upon awakening or after being seen.
1. Sweet dreams and dont let the Cum Monster suck.
2. If you don't empty your ballsack regularly then you'll get a visit from the Cum Monster!

A Cum Monster is somebody who looks like they just jacked off and walked out their door wearing whatever they found on their bedroom floor. They can be found in most public places. Cum monsters don't really care about what people think of them and often don't shower.

The disowned brother of the Cookie Monster, he loves to guzzle a certain white juice. Beware the Cum Monster, for he will suck you off while you sleep and grow stronger with every nut.
