Hi, Gvazdas: how 'bout:

• Necrobutcher
• Problems?
• Nice to Meat You.
• Argument

Flare gun: Rooty tooty point an- IT BURNS
Black box: My meat, your poison. ("One man's meat is the other man's poison", if you didn't figure that out)
Jarate: Radioactive waste

Just the first things that came to mind. It's much more fun to find something that relates to your playstyle, though.

I would name the flare gun Ric Flare. WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!

Flare gun = fart gun

Karku: Gun of the damned

Name the Black Box "You've been Rickrolled!"
;)

jarate: Hales own piss

Well, MY Black Box is called "The Argument Invalidator".
For Jarate, I guess you could make some joke about lemonade or "Greased Jar of Grease", implying that you're carrying it for some reason other than throwing it.
Flare Gun: "Can you find me now?"
