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!

A cactus shaped like a cock, but can also be the lovely male on virtual space amino. He's a cool dude that everyone loves but he is a huge dick, that's why his name is cocktus. He likes to be called cockie.

Everyone: nobody likes you george
