Contraptions

Contraptions is the slang term for the crap players make in-game.
Often used to trap/kill noobs, these can vary from a standard chair that sets you on fire, to a needlessly elaborate contraption used to humiliate people without killing them. Favourites include:
* Headcrab cage.
* 3 crates stacked on top of each other.
* A bad-ass claw machine taking up about a 10th of flatgrass.
* A flying chair which you have to ignite to stop the assholes from taking it
