Someone who touches bums, with or without permission.

Anatidaephobia is defined as a pervasive, irrational fear that one is being watched by a duck. The anatidaephobic individual fears that no matter where they are or what they are doing, a duck watches.

Anatidaephobia is derived from the Greek word "anatidae", meaning ducks, geese or swans and "phobos" meaning fear.

The blue gloves that firefighters and paramedics put on when waking up passed out bums in public places.

Taken from the words bum and toucher. A bum toucher can be defined as someone who touches either alot of bums or perhaps one frequently. It can also be used to describe somebody who touches thier bum with other or perhaps their own.
They could also be known as an "ass feeler"- somebody who takes it upon themselves to feel others bums without their concent, which is frankly quite rude.
