backer inner 

Male who is a bottom and is seeking a male top for sexual encounter at forest preserves.

I asked how you can tell the difference between a top and bottom at forest preserves. The guy said a bottom reverses into parking spot which they call a backer inner while a top pulls in forward. Innuendoes match the parking.

backer inners 

single men backed in to a parking spot at a forest preserve waiting for a hook up from other men.

Hey Bill it was pretty scary at the forest preserve today with all those backer inners looking you up and down as we drove in here.

Backerinner 

Somebody who insists on backing their car into a parking spot, regardless of who it inconveniences.

It takes long enough to find a parking space in a busy parking lot without a backerinner piece of shit taking life and a day to get into their damn spot.
