Picking Up Pennies

You know when you're roaming around Portland and you see that one person high on life attempting to tie their shoes?
Tweakers. More specifically, fent heads swaying in the wind. You know the stance.

It can be used liberally to blanket the behavior of any high, not just the bad ones.

"Oh shit, dude is over there picking up pennies."
"We've got another one out there picking up pennies!"
"Dude was so gone he was out on main pickin' up pennies!"
"Dalton ripped the bong and started picking up pennies at the concert!"
