This phrase can either refer to two things:

1) The map named 'Rust' on MW2/MW/CoDM, which is where the term originated
2) The game 'Rust', which is also an FPS

Each have their own backstory. The cod map is often where the most brutal bloodshed take place, while the game itself is brutal on a whole other level.

My friend does this all the freking time.

It mostly occurs when you challenge or get challenged to a 1v1. and you or the other player get to a point of the map were they can kill you at any and all spawns. As soon as you spawn, you get killed.

This is one of the most annoying things in gaming.
