A terrible disease that sticks your once perfectly normal(ish) mind into a dirty gutter, hense gutterbrain. It will make you think dirty all the time, make any sentense dirty, ect.

P.s. This disease is uncurable.

GOOD LUCK FELLOW GUTTERBRAINIANS.
Catrina and Maddy Have had gutterbrain since they found out where babies came from.
