Combusken 

A Pokemon that looks like a yellow dick with arms, legs, and a cannabis leaf on its head. Aside from that, it is the evolved form of Torchic and gained the Fire/Fighting type. Once it reaches level 36, it evolves into Blaziken. This Pokemon started the Fire/Fighting type evolution for the next 2 Fire-type starters. Good thing Delphox broke that chain.

Pokemon Emerald: What? Torchic is evolving!
Congratulations! Your Torchic evolved into Combusken!
Player: That's literally a fucking dick...

Mongolian Nut Combuster 

A sexual encounter involving 3 males. One fully naked man is standing with his scrotum dangling and his legs spread wide. The two others are wearing full Mongolian native tribal gear standing 10 yards away from the man. One is facing his front, and the other is facing his behind. They begin chanting, and when the chanting reaches a climax, they both charge head first and torpedo dive into male 1's nutsack causing a full explosion, Then males 2 and 3 use the blood and mutilated testicles to masturbate.
