hair-trigger shitter
You know you're a hair-trigger shitter when you drop the bomb and bolt before the toilet even stops bubbling. No drama. No pain. Just pure, unrelenting pooper power.
I had to go so bad I left a trail of poop on the floor.
I went in the bathroom and came out 30 seconds later like nothing happened.
I sat on the toilet for 10 seconds and then ran out like I was on fire.
