The mindless state entered when one is about to shit one's self and one frantically searches for a bathroom. Never get in the way of someone in the grips of the dumprush. They will run you right over in their haste to go poo. Even the glopblocker cannot stop the dumprush.

"Sorry man, I was in a dumprush"
"That's cool, bro."
