"If the police catch you with more than three rolls, you'll be charged with manslaughter."
"Dude, these tabs are double dipped!"
Retarded made up strain names for weed that always include the words "Afghani" or "Kush." For example, "Try this Purple Mindfuck Afghani Kush."
People that don't know one bit of the science behind various drugs, but insist that they will melt your spine, put holes in your brain, turn your eyes into flaming balls of radioactive magma, and shit like that. Then when I try to explain how they actually work, they dismiss all of it and insist they are right because they "just know."
When dealers give you a short bag and insist it is your scale that is to blame. Similarly, I had a dealer sell me a "gram" of molly that was only .7 grams. He insisted that because my scale only went to one decimal, it was a full gram. Fuck people that can't do simple math.
