Spermicterus 

When a guy hasn't had sex in a while, and all the sperm that he hasn't cummed, "backs up" into his brain. So now all he thinks about is having sex.

A play on the condition, kernicterus, in which unconjugated bilirubin deposits into the brain of a newborn, causing severe physical and mental problems.

Man, John has a case of spermicterus. All he does is talk about sex. He really needs to get laid.
