Scott(y) Skelton A.K.A. Mr Double AB Triple C Double D (long nickname) is a tricker from Brisbane, Australia.
Scott Skelton is known for his uncanny ability to do double and triple twisting moves with great ease. He is recognised by many as the leading twisting styled (power move) tricker in the sport thus far.
His nickname comes from the fact that he has landed double atwists and btwists (AB), triple cork (C) and double double leg twist (D). All put together it's Mr. Double AB Triple C Double D. He is also (officially) known as Mr. Double ABCD (because it's easier to say). He was first nicknamed so when the first 3 moves he did of the day during a grass session were the Double ABC. Since that day he was the first to land a double double leg twist on flat. He is also given credit as the first person ever to land a triple cork.
