Rail Gun

Means 2 things:

1) A weapon under development. Used against a giant robot clawing the Pyramids of Giza.
2) Ability that can fire straight electric shots, with anything iron-made as head.
3) A tomboyish woman who loves wearing boylegs, loves a frog mascot, has more than 20,000+ clones and fell in love to an unlucky bastard named Touma.

1) Rail Gun is a futuristic weapon.
2)Agent: I want a prototype weapon called a Rail Gun.
Ship Captain: That's classified.
Agent: Don't talk to me about CLASSIFIED!
3) A Rail Gun shot was deflected once again by the UNLUCKIEST BASTARD on Earth.

custard gun

Australian slang for a penis, neatly encapsulating the description of how that part of the male anatomy shoots with great force a fluid that ever-so-slightly resembles a globular, liquid dessert.

Also Custard Gun was the original name of the legendary 1990s Brisbane AU band Custard: name truncated for obvious reasons!

I drizzled my gf's donut with a healthy glaze courtesy of my custard gun. Mmm!
