one-banger

A one-banger is simply slang for a single-engine airplane like a Cessna 182 or a Piper Cub.

{Julio} Hey Jesus, there's a single-engine airplane taking off from the airport over there.
{Jesus} Julio, you mean to say that there's a one-banger headed this way?

Birth One

Taking a massive shit. To gestate and birth a turd of notable size and proportion.

I’m headed to the shitter. I’m fixing to birth one.

I just had an ass splitter. I knew I was about to birth one. The turtle was peaking earlier.

Eating all this curry guarantees I’ll birth one that’s real wet.
