Ten Cent Pistol 

Drugs (usually heroin) laced with lethal amounts of poison. Arsenic is common. Used as revenge against addicts and dealers alike.

"You cross me, you get a ten cent pistol."

Ten Cent Pistol 

Low-rent, heinous substance that disfigures you, like homemade napalm.

Because they ruined her name
Well, she hit them with her ten cent pistol
And they've never been the same
