a type of sex ploy wherein you are with your counter part in the shower. hitting from behind. but, being very nice and gentle (just the tip). then you intimately lean forward and whisper into her ear "gecko" quickly follow this up by ramming them with your full cock. they will attempt to climb the wall like a gecko.
