Mummy Dust

Mummy dust is things that have happened in the past. They're history, old news. Things that people won't let go. When old people talk about "well back in my day." Or people who are always bringing up stories from high school. Shit's mummy dust.

"Corey Colteaux is always talking about high school, always bringing up mummy dust."

E-40 Revenue Retrievin': Day Shift (Everyday is a Weekend) lyrics -
"saw some suckaz I don't trust (what they do)/
got to bringin' up old mummy dust/
pullin' up the past/
talkin' loud like a big mouth bass"

Mummy Dust

Really terrible dried up marijuana....so dry and brown that not only will you most likely not get high, but you will most likely get sick (if you don't get sick from smoking it, you will get sick from the sight of it). Stoners know that you go to great lengths to smoke, and will smoke almost anything, but mummy dust is just so bad and not worth it. By the time you light the blunt, the weed has already disappeared.

Guy 1- "Yo man you got any of that weed left?"
Guy 2- "Yea i got like an 1/8th of mummy dust left"
Guy 1- "Fuck that man I don't wanna get high anymore"

a cloud of skin, feces, dirt and scalp dandruff, that can be found on the unwashed clothes and bodies of homeless and or drug addicts. Similar to the dust found in a mummies crypt.

Bruh, I gave this homeless guy a ride home when he pop'd out of the car he left me in a could of his mummy dust.
