What is the definition of Nukem?

A 'nukem' is a term that's as outdated as the 'talking toast' fad of the 90s, but with a whole lot more nuclear power. It's like saying someone's a 'radioactive teacup' - absurd, yet somehow fitting due to its nuclear connotation. Here's a edgy example: "I can't believe he decided to upgrade his Wi-Fi with a nukem - it's like putting a nuclear bomb in your router, but with less smoke and more 'I'm sorry about that' text."
