Just like the bad boy, the sexy, skanky guy has a certain je nais se quoi. You know you shouldn’t date him because you’re just not sure he knows the meaning of hygiene. Does he really wash his hands after using the bathroom? And you just don’t know which groups his member has joined. But then again, a little dirt looks good on some folks. And you have to admit that sleazy guys don’t lack personality. So we’ve compiled a list of the best sexy, skanky guys. Most of our picks have a natural ickiness that makes them bed-able, but then others are on the list for a more specific reason, like Mickey Rourke for his role as Marv in “Sin City” and Kevin Federline for, well, everything.
