A designation meaning "one who is better left at home", that is always intended to torment a male of low status by causing him to believe his sexuality is in question. It is often repeated, in rare instances chanted.
"Hey look, it's Timmy the homelover. Why'd you come out homelover? A homelover like you should be at home, like a good homelover, with your homelover brother, loving your home. Ya homelover!"
It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.

Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.
Man, I just watched the funniest nutshot video ever.
