one banger

When one knocks out a belligerent asshole with one clean punch.

"Chad was trying to fight every guy at the party until Brian gave 'em the one banger. Kid was snoring before he hit the floor"

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?
