Bun run

When a person goes out and picks up food either for themselves or for multiple people.

I’m going on a bun run to McDonalds to get fries.

Midnight Bun Run

A Midnight Bun Run is a trip in the middle of the night one would make to a location to join another in sexual activity.

Mark-"How was last night?"
Joey-"Dude it was awesome, I went on a midnight bun run to Sheila's house!"
Mark-"Dude, awesome!!!"
