seahorse

A quarter-note rest in music, because of its shape.

This music is boring! There's nothing but seahorses for twenty bars!

Seahorse

When you tickle a person behind the knee with your foot: Used to induce an orgasim. Not a 100% guaranteed.

"Hey, today in business class. I gave my friend a seahorse."

"Really?"

"Yeah, but he didn't come"

"Shame..."

seahorsing

Injecting large amounts of tadpoles up a mans ass until they explode out of his anus. Very similar to the way a male seahorse gives birth to its young.

"I asked him if he wanted to try seahorsing and he looked at me like I was some kind of freak!"

seahorse

derogatory term for Swedish men because they are given maternity leave when their wife is going to have a baby, so they also stay home to take care of the newborn (like male seahorses that take care of baby seahorses).

That (man's name) is such a fucking seahorse, slacking off from work cause his wife popped out another kid...
