Whenever someone in a seemingly good mood goes bipolar and starts throwing objects on the floor and screaming like a banshee as to make their point, kind of like kid's in the grocery store who aren't allowed to get a candy bar.
Inspired by my history teacher's wonderful meltdown in front of class today.
Oh, man! That guy just got Brashered!
Whoa, she is totally being a Brasher today.
That guy is really Brashering his kids right now.
She just had a Brashdown! (instead of breakdown).
