Genocyber 

A mechanical monster formed by two psychic sisters. Often destroys anything in its path, including Hong Kong.

Also an anime that stars the monster of the same name.

"Genocyber? Yeah, that's the anime where even the kids get killed in gruesome, horrible ways."

"And so, Genocyber destroyed Hong Kong. Mysteriously, of course."

Genocider 

An alcoholic beverage made by mixing 6 oz. of apple cider, a shot of Captain Morgan's Spiced Rum, and a shot of Everclear.

I blacked out on Genocider at the party last night and woke up with a swastika tattooed on my forehead.
