At certain convenience stores or gas stations,usually in the hood, they make you "pay before you pump" to keep you from stealing gas, similar to a "trick" having sex with a prostitute or a "hoe". You have to pay before you "pump". This could make you feel like a gas trick.
I'm sick of gas trickin'!! How come I can't pay for my gas after I pump like they do in the burbs'?
