The point where ur penis is kinda hard and ur excited but still have ur pants on. You might be dancing with some fine slut and she'll feel a little bump comin through and grind that shit like she's fuckin got an itch.
Guy 1: Shit man, i got a semi erect penis when i was dancing with her.
Guy 2: Did she grind that shit like there was no tomorrow?
Guy 1: Nah she only likes nello and his big bulge.
