That's what I yell right before I fill up my diaper with liquid feces. I haven't had a solid bowel movement in more years than I can count.
I used to yell "Fire in the hole" but ointment I've been using stopped the burning sensation.
When I walk around naked without a diaper and air out my dick flaps, I like to bend over and yell "Thar she blows!"
Now you know.
