throw the rice in the fire

To go bat-shit crazy and do something extremely impulsive and self-destructive.

Did you see what Britney did to her hair? She really threw the rice in the fire.

Origin: on Survivor season 28 J'Tia gets pissed at her tribe because she thinks she is going to voted out, and throws the tribe's rice in the fire out of spite. Brandon also threw his tribe's rice in the fire on season 26.
