stray fart

Once somebody farts and it the initial smell has disappeared, but then the smell returns, this is referred to as a stray fart.

Can also be used to indicate that someone is hanging around like a bad smell and should leave.

I wandered into a stray fart over there, man was it smelly!

Haitham is being such a stray fart.
