After a man shaves his never-regions and leaves prickly stubble, his cock and balls temporarily resembles a skin coloured cactus, thus becoming a cocktus.
Hey Jenny, how did it go with Iain last night, did he give you a night to remember?
He sure did! I think he shaved his pubes a few days ago because it felt like he shoved a cactus up my vag! It’s was so fucking prickly, and now it’s sooo itchy down there...
Ohh dammmn Jenny! Iain stuck you with his cocktus, we all been there! Get some Sudocrem on that shit!
Last night that bitch I was with almost knocked herself out cold when she had her head too close to my balls as Cocktimus Prime was transforming. Dumb bitch, so I used Cocktimus Prime's main weapon, the baseball bat swing, and knocked her skank ass out anyway. All hail Cocktimus Prime.
Robin: So what was it, a cockroach or a mouse?
Lily: It was a cockamouse!
Robin: What?
Lily: It's some sort of mutant combination of the two.
It's as if a cockroach and a mouse, you know...
