A type of fart, usually wet, that tends to have a stronger and longer lasting stink to it than a normal fart, and can even seem to "follow" one around.
Sarah came by my department at work today and almost threw up when she smelled the lingerer I had ripped almost 5 minutes before she arrived.
Chunks of diarrhea that refuse to go down the toilet bowl after the first flush. Chunks that remain after the 2nd and 3rd flush are then known as Stallion Lingerers.
Toilet user #2: Ahh, shit! Johnny left some Lingerers behind!
