Beat Matching 

When you be smacking the sirloin and the rhythm matches the porn that you're watching.

Uhhh, smack, Uhh, smack. Man as a pasty red head from Oslo that's so rejected. I feel an affinity and a similarity to Tyrell from L.A. in the hit feature "Tricky Nicky get Sticky Icky (with my 10 inch black cock)" Oh check it out, I'm beat matching and I didn't even realize it, where do I send fanmail?
