The act occurs when a couple are having sex without a condom and the male does not "pull out" before ejaculating. The idea is that he is suppose to but it feels too good or he just doesnt give a fuck.

When a fucker (usually a guy) fucks another guy (fuckee) in the ass and the top of his dick comes out his mouth. The fuckee tries to pull at the dick but to little prevail, it just gets harder.

Derivation:
In Greece putting your thumb between your index and your middle finger and making a fist indicates discontent (similar to a middle finger), but symbolizes that man fucking the recipient in the ass. On an average day that would be a small penis, but not when its a sword in the stone!
Jakob was complaining about his throat hurting so i gave him the sword in the stone. That ended that.

Have you seen that video with the horse and that guy?
