Doing what is necessary to be done. AKA getting between a girl's vagine.
Guy 1: What happened with that girl last night? Did you neen the bean?
Guy 2: Nah, she wasn't all in, so I had to jerk off instead.
To explore the female. To get it in. Pounding a girls' twat from behind after a long night of drinking.
Guy 1: Yo man, did you indicate last night?
Guy 2: Yeah bro, we came back from the Bull and I had the drunk dick going on, so I fucked the tits out of her, then indicated her sphincter. Another great night at Montclair.
