Jack Off Sense
The crazy power you get when you can tell exactly when someone is about to walk in your room before you do, like you're some kind of psychic peeing in a cup.
My mom walks in my room like she owns it. I saw her shadow before she even opened the door.
I knew my brother was coming in my room before he even knocked. I was already hiding under my bed.
I could tell my sister was about to barge in my room before she even said a word. I was already in the closet.
