Taking a large dump so foul smelling that it is suspected of being part of a Mexican terrorist attack. Unlike a actual terrorist Dirty Bomb using radioactive material this is the Mexican equivalent using bean fueled Poo.
OMG stay away from the bathroom ! Dave set off a Mexican Dirty Bomb in there and it is unsafe for living creatures.
