A semenator is kinda like a Squirmanator
except probably not as cool. A semenator is extreme good at ejaculating a lot more semen
) than the average human. Basicly, anyone that you know that puts out enough to fill a glass is definitly 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.
