The technique of drinking some irresistible beverage with a fellow human being at the same time.

Did you see Jerry double-sipping that drink with his girlfriend?

doubledipping 

When you are having anal sex(with a TS, male, or female) and the person on top, pulls his cock out of the ass and then rams it back inside and then pulls it back out. Usually, doing it fast or slow....this can create a massive sensation of pleasure, due to the nerves around the anus.

Damn, your cock felt sooo good when you were doubledipping my ass and slapping/rubbing the tip against my hole!
