Dirty Shampoo

You are taking a girl from behind and just as your about to cum you pull out, blow your load in her hair and start to massage it in like your washing her hair.

I gave that girl a dirty shampoo last night.

Dirty Shamus 

When you stick your fingers in your partner's asshole and wiggle them until they're coated in shit, then pull them out and shove them in your ears.
