To drive your car through a small, and usually dangerous, gap in traffic.
The car in front of us slowed down suddenly so we had to gap it.
We were racing in the evo when we gapped it into the next lane.
The word gap it originated from the suburban ghetto of mascot which means to leave the seen of a crime or place.
homie 1: man we're going to get caught!
homie 2: you're right lets gap it geeh!!
