rattlesnake wiggle
the act of having a limp dick (must be gifted enough to have a large limp dick) and having a girl about to give you head on her knees and while standing swing your hips from side to side making your dick smack off each side of her face making a noise, or you can do it without the girl and make it snap off each one of your legs,, must make noise!!!!
i gave her the rattlesnake wiggle last night and she loved it
