Because they say Vintage Undertaker! when he does it
Yeah but then there'd be an entire series of Vintage moves for different superstars. Michael Cole says that WAAAYYYYY too much. It's his "Slobberknocker". Anytime a move is used that doesn't have a Proper Name he just says it's Vintage Them. Like every Orton match ever. His powerslam or spike ddt are always vintage Orton.
