A condition in which a disgusting slut's dirty meat wallet cramps uncontrollably due to the the pressure it has received from years and years of getting blasted by hot and sticky man milk. Also known as a period.
Barbara came to me today complaining about painful cramps. I diagnosed it as a severe case of semenitis. I recommended that the dirty whore stops geting her ax wound pounded and creamed in until it heals.

One who emits ridiculously large amounts of semen after sufficient stimulation to his manhood. Does not mean he has a large didgeridoo or is immune to the feared premature ejaculation. Not too much is known about semenators...

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.
