A bowel movement where after the main dump, there's still a piece of turd that is on the verge of coming out, but you just can't get it out. Called a Teddy KGB because it's just "hanging around". Will usually result in a terrible wipe where at least half a roll of toilet paper is used.
"Well, that sucked. I was in there for 25 minutes. It was a real Teddy KGB."
