The act of rubbing together, or 'tribbing,' between a woman's breast and another woman's vagina.
Jessica's legs opened almost automatically at the sight of Martha's ample but firm bosom; she had been dreaming of this moment for the longest time, and now finally some dovefucking was on the cards.
From A Bird in the Bush by Barbara Cartland
Someone who is in such a drunken state that they are completely and utterly delirious.
Yeah, that girl last night was so drunk she was rolling on the ground while chanting "AVADA KEDAVRA." Dude, I just sat back and watched her. Defuckinglirious, bro.
Wasting time, lazing around, procrastinating. When you're supposed to be somewhere, and you're late, you're dogfucking.
Note this definition has nothing to do with actually having sex with canines.
Guy #1: Is Dave coming?
Guy #2: Who knows how long he'll be, he's been dogfucking all day.
