Party hat

This is given to an opposing player in the Halo videogame series when a plasma grenade is stuck to their head. The name originates from the blueish glow right before the grenade detonates.

Halo player 1: Here you go, a personal party hat just for you! *stick*

Halo player 2: Whah? *booom*
