squirreled back

When a drug addict is extremely dosed on methamphetamine (crystal, ice, speed, crank, shit, glass, etc.).

Typically this persons altered perception, and undeniably humorous state of confusion, can be a bit squirrely.

"Dude I'm fuckin hella squirreled back right now, I seriously won't sleep tonight....Fuck Man..... whatever I'll just call outta work, I'll be to fuckin bug eyed to go in and shit.... haha"
