A meme that is actually older than everyone thinks it is. Originally spawned from the YouTuber Pyrocynical, who received a tweet from BamanBoi in mid 2016 that read, "you're mum gay".
Pyro: @BamanBoi - ur mom gay

(Pyro chuckles softly and then erupts into heavy laughter)

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