gallstone - A rock so stubborn it won't leave your body unless you blast

A rock so stubborn it won't leave your body unless you blast it with sound or let it out through your peenie like a cursed bean

I had to get an ultrasound to get rid of my gallstone, and it was like getting a facial from a robot.

My doctor told me to either let my gallstone out or get it zapped with sound, and I chose the sound.

My gallstone was so annoying, I had to let it out through my peenie like it was a tiny alien.
