Get the meanderthal mug.
A person with nowhere to go and nothing to do who wanders the sidewalks aimlessly in a swervy, slow path that blocks the paths of people who do have somewhere to go and something to do.

An old person who walks at an extremely slow pace. (This word is a combination of "meander" which means to walk slowly with no apparent destination, and "neanderthal" which refers to something old, ancient or prehistoric.)
