Any girl that can physically hook up or have sex with a guy. Preconditions usually include a pulse* and lack of any male genitalia.

*Pulse sometimes optional.
Guy 1:Dude is that girl breathing?
Guy 2: Yep barely, but she's got a pulse.

Guy 3: Sweet, so she's griffable. Alright leave the room, it's boning time.
