When people are describing Ben Askren as a "funk" wrestler, they're probably talking about his particular style of attack. Funk wrestlers are guys who use high risk moves. Randy Lewis is another good example, I think. He would let you grab his leg just so that he could counter and throw you. Typically, these wrestlers love scrambles, love being on the ground (where they can use their "funk" to their advantage), love throws, love counters, etc. Most of the time, funk wrestlers are long and lanky. This one guy I know, he's kind of mix of funky wrestling and the famous "John Smith" style of wrestling, he will take a bad shot on purpose just so that he can sit out and finish.
