What's the worst or shittiest thing you've ever done irl?

I'll go first.

About two years ago in my first year of university while two friends and I were studying late at night a girl who was in the same room as us left cuz it was getting late.

About 30 minutes or so later we noticed she left her IPhone charger and plug right there... It was free real estate after that.

This was two years ago and I am slightly changed man now.

Here's a pic of the plug I took that I'm still using at the top btw(one of my other friends took the charger):
