Lane 4 

The middle lane in an 8 lane race. Usually applied to swimming, where it is the fastest lane.

The middle swimming lane, where the fastest person swims in order to minimize waves from other swimmers, and let him/her own more

I freaking own everyone! I shouldn't have to swim prelims, the officials should just put me in Lane 4 for finals.

4 lane skid mark

After leaving a huge crap in the toilet you proceed to flush, the poo leaves a mark on the base of the toilet so large it covers it entirely.

I just left a 4 lane skid mark in shitter.
