i'm a female. 
my sister and i were in a local diner and had a huge ice cream, we were finishing up and i needed to use the restroom. my sister went and waited in the car while i did my business. currently i'm on my period and it's a heavy flow day, my stomach was all grumbly after all the lactose, so i not only needed to change out my pad for period stuff, but i also needed to poo...real bad. 
the women's restroom was a single room and it was occupied, so in an emergency i opted for the mens bathroom. i went in, locked the door, and had a bad case of the squits. when i was finished i got up and looked in the toilet, it was real bad, a ton of period blood and poo filled the bowl and it looked like someone had a severe internal colon bleeding problem. i was pretty grossed out, but when i went to flush it did nothing...the toilet was broken. it wouldn't flush. i was mortified and tried taking off the back of the toilet and fixing it, my dad's a plumber so i figured i knew some stuff. i couldn't fix it, so i panicked, ran out asap,  and got in the car, then realized i had left my car keys in the mens room on the counter. i had to go back and retrieve them before some guy went in and knew what i had done. i made it in and out okay but i've been thinking of the poor sap that has to witness what is in that toilet, and fix it....

TIFU by using the mens restroom.
