The pesky last remnant of an otherwise successfully-clean turd, often smeared upon one's grundle when wiping. Sometimes referred to as a hole hanger
There must be some secret pact between turds and toilet paper -- I never seem to get a bungdangler unless the roll is nearly empty
this is a really awesome transition that would rule to ride a skateboard or bike on, but unfortunately its upside down. can be found underbridges, in archways, etc.
dude one day when there is no gravity on earth we will ride that bungdangler
