It used to be what this turtle pokemon would yell in a hoarse voice when it squirted water out of it's mouth. Now, it what you yell when you shoot your load into a girl, preferably imitating the hoarse, messed up yet triumphant tone of the turtle pokemon as your dick, squirtle-like, shoots it's fire fighting fluid.
girl: Oh Baby, that feels so good, please don't shoot into me!
guy: Squirtle!
girl: Fuck, you are retarded. And now you are going to be a daddy.
guy: Squirtle!
girl: Fuck, you are retarded. And now you are going to be a daddy.

A word used to substitute "shut up". This has dervied from men who used to play pokemon, a popular tv-show. They were tired of one of their friends talking and they said "squirtle-squirtle."

The sexual act of shoving a garden hose up your partner's anus until the water comes out of their mouth. The spiritual successor to charizarding.

The act of forcing yourself to vomit after a night of drinking by chugging a lot of water. The result of this is vomiting straight water, which looks like watergun attack from Pokemon.
