when the girl you're giving it to doggy style passes out or falls asleep and you don't see it as a reason to stop
Guy 1: Hey man, did you and your girl make it home from the party the other night?
Guy 2: Yeah, we got home and had great drunk sex. Was hitting it from behind and she passed out, so I just kept it going all groggy doggy.
Guy 1: Sweet, love the groggy doggy.
