A tiny circular piece of fiber, often found in in the carpet of play or otherwise recreational rooms, which is oftentimes used as a cock ring for LegoPeople.
I found a toomule while playing with Legos. I tried it on, but now it hurts badly and I cant get it off.

A strange, almost microscopic circular piece of fiber that appears to be some kind of plastic, possibly used as a cockring or choker for gnomes, pixies, or Legopeople.
My Lego dude's sportin' a toomule for his night out at the red light district.
