The sexual act of ejaculating into a partner's anal cavity and then farting out the semen. A woman who perfects the action is known as an Old Faithful.

While shoving 4-5 vodka soaked tennis balls up her twat. The Russian Tennis Geyser is performed when the woman in question increases pressure in her snatch by preparing to queef, then letting it all explode out at once. There are only 5 known casualties that were sacrificed in the making of this technique. This is generally very dangerous and should not be attempted unless you are a professional whore.

Cum in you? Did I cum in you? Bitch, are you blind? That was a Christ-boosted jizz geyser! I'm done with you. Don't call me anymore.
