A phobia gay (still in the closet) people made up so they would not look or sound gay when they sit to pee. Usually gay people try to blame straight people of doing it even if they don't do it so people will not think they are gay.
Dan: LOL, I didn't hear pee hit the toilet, did you sit to pee, do you have tricklephobia?
CLo: Ha, I went to poop dude, are you gay? usually gays try to blame us about doing that, weird?
