Red line
The boundary of the map behind each team's spawn, and by extension the habit of playing pressed against it.
Also known as redline, redlining.
Crossing the red line is fatal: the vehicle is destroyed after a few seconds. Backing onto it is not, which is why it is where a losing team ends up, and why redlining describes a player who never left it.
It also has a use. A vehicle pressed against the far edge cannot be flanked from behind, so a last stand there is sometimes the right call rather than a symptom.
