Was DDP/Kimberly a proper spanking? If you mean OTK, then yes. As far as we collectors are concerned it wasn't proper at all because we got teased with some great positioning and 1 swat, and then we were blessed to gaze upon the cheery faces in the crowd as DDP continued to spank her.
Kimberly had been trying to break away from her husband to establish her own star, some of her antics included hitting him with a guitar and pouring a bed pan over him in the hospital. The spanking was well deserved, it was just flabbergasting that they went to such lengths to set up the spanking and then when it was show time they got shy.
Most Pro Wrestling spankings are face spanks bad girl. There are some exceptions, such as Billy Jo Travis/Toni Adams. Travis handcuffs Toni's good guy husband to the ropes and forces him to watch as he spanks his wife in the middle of the ring. Another case is when bad guy Jim Cornette holds Sherri Martel for Tammy Fytch to spank her. Also when Lizzy Borden spanked Kristy Myst and recently Major Gunns. Dawn Marie spanking Tammy Sytch and Francine would fall under this category too, I think.
