Scissor Serve

To to scissor serve somebody they must give you money expecting a certain product in return.

you take their money and and whatever product you purchase you keep half of it for yourself and give the purchaser the other half acting as if it was whole and no foul play had occured.

I give this dude 40 bucks for an eigth and he comes back with 2 grams like thats what was given, motherfucker tried to scissor serve me.
