A form of sexual activity first discovered in Newport. In the shower, when a bloke slithers his sausage inside of a females bumhole accidentally and the woman then scatters up the wall to get away.
Did you hear about Mark boy last night? He did the gecko on Tracy.
Gecko style is when you are doing a woman from behind (refer to doggy) but in a standing position against the wall. As you are going full pelt you pull out and jam its straight up her arse and watch her try and scramble the wall like a gecko.
I pulled out and gave her the gecko style, she nearly clawed the paint off the wall.
