Mummy Dust

Mummy Dust – a slang term referring to components, ingredients, or accessories that manufacturers add to their products to enhance them, but which have no useful, or scientific basis for inclusion.

When you hit a really stupid person in the head, the only thing that comes out is 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.

Slang for ketamine

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.

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.
