When a guy and girl friend of yours are piss drunk and you determine they shouldn't do anything that involves their genitals, because 1) she's too drunk and horny and she really is a good girl, 2) he's got a girlfriend in another state who he wants to be loyal to when he's sober, 3) the girl just denied you (doesnt help that you're sober) so you dont want him gettin any, and 4) condoms will probably not be used. Just let the fuckers engage in spooning for a couple hours.
Man I hada cockblock my friend cause I know the girl he's with, and she's a good girl and doesn't deserve gettin knocked up or anything.
