tweakerdoodle

A tweakerdoodle is someone who has used so much methamphetamines that they no longer have a functioning noggin. Tweakerdoodles can be seen walking on the side of the road collecting rocks, pretending to landscape piles of trash in front of their trailers, or scurrying around town.

Lock the doors there's that tweakerdoodle again!

Good Lord, look at that tweakerdoodle!
