aka KAK - Knocking Air Knuckle, used in conjunction with SKEECOO SKEECOO. A simple, but effective visual using one hand in the air in a motion that looks like knocking on a door. For an incredible effect, try a double knocking air knuckle. Wow, that would be something!

"I told Franny I would go over her house after work, but I'm not really diggin on her any more. I never go back on my word though, so I went over alright and gave her door the ol' knocking air knuckle and then busted outta there!"
