What is lanesplitting?

The act of taking one's tongue and licking between the two balls.

Bro, she was literally lanesplitting me last night.

Riding a motorcycle between two traffic lanes between cars.

There were a ton of cars on the roads during rush hour, so I started lanesplitting to get through traffic faster.

Riding your motorcycle between endless lanes cars on the freeway.

Damn this traffic jam! If I were on my crotch rocket I could be lanesplitting all the way home!
