Eat hot knife
You stab someone with a hot knife and take their dogtags like they’re stealing your lunch money. It’s the worst way to die, and people laugh at you like you’re a joke.
I got hot knife’d and my dogtags are gone. I’m just a sad soldier now.
He ate hot knife and now I’m just a tagless loser.
Ate hot knife and now I’m just a ghost in the game.
