When you smack your dick on a girls face as your cumming, usually after reaching climax from a blowjob.
Jeff: Yeah man I party smacked my bitch last night, she got soaked!!!
Tony: Thats crazy dude, she deserved it for giving you blue balls last time.
In non-circumzised men without a hard on and probably a small dick. Rolling the foreskin on your dick inwardly all the way, the cock gets pushed back into the scrotum hiding it.
Henry: I pulled some cock magic on my girl last night, its like the new mangina
Ajay: Dude, thats fucked up why did you try that.
