RIP to a real motherfucking pimp. I saw him smack the living bullshit out of a bitch on video before.
He did it the way you need to. Make you hand as stiff as possible then swing open handed and aim square for her cheek.
I did this to a motherfucking bitch before, dumb ass hoe had to wear my fingerprints across her face fo 3 days. I smacked the hotfuck out of that hoe.
