Clumpy

[Monty]

A [homeless man] with middle fingers missing on both hands, giving the appearance of [crab] like claws instead of hands - or [clumps].

A Clumpy is also a popular dance move, where a person walks sideways like a crab and imitates picking up cans with their outermost fingers. An odd, distorted face usually accompanies these movements.

[Julian]
