sperm competition

The theory that the sperm from two or more males will compete with each other inside a females reproductive tract to fertilize her egg.

Sperm competition should insure that only the most virile of males father offspring.

sperm-donor

Any guy looking to get something for self gratification by either shooting his load into a jar at a sperm bank and getting paid for being a jerk-off OR by sweet talking a female into letting his loser-ass fuck her and when she gets pregnant by him he punks-out and won't daddy-up.

Mr. Squirt, aka sperm-donor, went to the sperm-bank where he made a deposit and got a withdrawal because he needed money to impress the hotty he had a date with that night where he would make another deposit but no withdrawal.

Spermal Detonator

A hilarious euphemism for any kind of nut shot imaginable...with a Star Wars twist!

I totally dropped a spermal detonator on my girl's tits and immediately went back to ruling at The Force Unleashed!
