A Smut King (also commonly known as "Smut Lord", in more rural areas) refers to a dirty man-whore that sleeps with any and everything, regardless of weight, color, disease or species. He is often held in high respect (and disrespect) by his close peers. Smut Kings often partake in very disgusting and deviant sexual acts, including but not limited to, the Dirty Sanchez, Cleveland Steamer, and the infamous Hot Carl. To be associated with a Smut King is both an honor and a tragedy, a blessing and a curse.
Dude, I used to think that guy Alex was a pimp. After what I heard he did to that girl Kayley at the apartment last night, he's definitely achieved Smut King status.
