Fakin Jacks 

In the 80's during the crack cocaine kerfuffle you walk up to the dealer you don's say, "Crack" you might get knocked out. I've seen it so, Instead someone came up with the word "jack" this was the common term being used now. Gimme a few of them jacks man. Now if you got ripped off because someone put planters peanuts in your vial or the fake crack they were selling in the smoke shops back then and sold it to you that person is "Fakin Jacks"

Faking jacks

The original term comes from the crack game. It means to sell a crack fiend something other than crack. Instead of crack, it is substituted with soap, plaster or some other substance in order to steal the crack fiend's money.

Raheem sold me 4 Jums, but was soap. He is faking jacks

Half steppin on a robbery. Robbing someone and then giving them their things back on the spot. Then bragging about it.

Dude faking jacks.
