Cum in your hand then either slap her on the ass or face, with force to leave your creamy mark.
She was a bitch last night so I gave her a cream slap to the face.

Get the cream slap mug.
Similar to a mushroom slap but with the added bonus of doing it after you've ejaculated and your penis is covered in semen.
Guy 1: So how'd it go with Julia last night?

Guy 2: It was awesome!... Up until she just walked out after I Cream of Mushroom Slapped her in the face...

Guy 1: Rough dude. Guess she just isn't into that kind of stuff.
