Dan: Hey Mark, you remember that crazy guy on the bus that was masturbating?
Mark: Yeah man, it was fucking sick.
Dan: Yeah, well you wanna know what his name was?
*Dan smears shit over Mark's upper lip, leaving a shit moustache (a dirty sanchez)*
Anyone who thinks it involves the deliberate wiping of shit with fingers on a partner's face is a know-nothing fucktard.
Its like vanilla Ice cream when your starving for chicken..
