A semenator is extreme good at
ejaculating a lot more semen than the average human. Basically, anyone that
you know that puts out enough to fill a glass is
definitely a semenator. Can also be used in relation to liquids of mass amounts, see examples.
1. My ex-boyfriend was such a semenator.
2. Dude, that guy's
sprinkler system puts out so much water, I'm
not even sure why he hasn't won
the semenator award yet.
3. I wish I was a semenator so I could have kids.
