Moments before blowing your load, remove your penis from the vagina or asshole and cum in your hand. After your hand is full of cum, you smack your partner in the face with the cum filled hand, thus performing a Dirty Collins. Smearing is encouraged upon completion.

When your getting a blow job and your dick makes her throw up, not be size of the size,but the smell. You then use the throw up covered dick to slap her face than proceed to do anal.
Girl: He has a nasty ass dick that literally made me throw up. He was salty so he pulled a dirty collin.
