Like docking, it involves two, usually homosexual, men where the head of one penis is tucked/hidden in the foreskin of the other. However, the "active" version involves one step further. This is when the "docked" individual uses the foreskin of the other to "masturbate out" both involved parties.
Docking alone wasn't cutting it. Therefore, those two went into full on active docking.
The art of screwing someone over or out of something; fucking with someone in a funny or messed up way; telling someone some twisted bull shit to get your way or out of trouble... like a pig that fucks with a screw-like dick.
