GBBL... when LOL just doesn't cut it
by jack6128 July 26, 2008
Gushing Bloody Bladder Leakage. The excretion of significant amounts of bloody urine during mictuation. Normally occurs due to lack of STIs despite frequent unprotected sex.

Current hypotheses suppose that this is naturally evolved mechanism in people who have repeated sexual intercourse without protection and somehow manage to avoid infection, to teach them a lesson.
Jafooli had slept with 15 girls, and a transgender person, in the last three weeks without protection. He had just got his STI test results back and was delighted to be given the all clear. Unfortunately he went home and found he had GBBL when he sprayed blood all up the wall of his bathroom.
