This Is Horrible
Some beach fails are easy to laugh off and go about your day. Seeing something like this might just make it hard for you to ever look at a beach day the same way again. Even just getting pooped on by a seagull is pretty gross. We can’t imagine following that up like this.
We have to wonder — who was the first person to break out of the horror to tell the OP’s dad? What was his reaction when he realized what the “sunscreen” really was?
