Define Fill In The Gaps Meaning

Fill In The Gaps
When it’s rush hour traffic and cars are desperately trying to get into the lane you’re in. You fill in the gaps and do no favours for them, as they never for you.

Tyrones head: “come on, Tyrone, fill in the gaps. Don’t let the white man in.”
Tyrone: “come on you asshole!, I’m letting you in!”
