the cursed cumstain 

after getting it good you pull out before you finish. then ritually kiss her forehead and chant made up shit before busting one on her face. then with your finger you rearrange the cum to look like an anigram or something cultic. then you slap her in the face because she is evil. you then scream like a girl and call her cursed.

guy 1:"bro, she had it, she had the cursed cumstain."

guy 2: " bro, you gave it to her.

guy 1: it still counts...it was evil
