A dump so fiery and ass engulfing that your sphincter literally lights on fire. The person enraged by the passion of unsavory anal singeing then takes any object close to him and runs through the neighborhood wielding it, killing or maiming anyone in his/her path. The objects usually range from domestic cats to live people.

Mommy, I want to be a Dump Berserker for Halloween, you better make the dirtiest tacos that night.
