The Joker

After having sex with a girl on her period, you slap your penis on each side of her cheeks next to her mouth. Thus creating a red joker face, while saying "Why so serious?".

After ejaculating far too soon and noticing the look of disgust on her face. I immediately pulled out my blood covered dick and slapped her on each side of her face, while asking "Why so serious?", And the Joker smiled.
