Your mom gay is part of the BOFA spectrum of diseases. This disease is caused when someone has untreated Ligma that doesnt transfer into E-TMA. This disease causes the patient to say "Your mom gay". When they say this, if nobody says "no u" within 5 seconds, everyone within a 5-mile radius loses their jobs, homes, dignity, or even life. But, if someone says no u, the patient has a 98.4% chance of dying. If the patient has untreated ligma and surpasses the your mom gay stage, they get the unstoppable "your mom gay lol" disease.

Universe: *holds breath*
Random nibba: no u
Universe: *exhales*
Person with disease: *dies on the floor*
