Gulf of Mexico, Mexico - Ewan M
One time, I was visiting the sandbanks near Cancun, Mexico. I went into the water and when I got in, I soon felt this unbearable pain in my thigh. It hurt so bad: it was from a jellyfish. When I walked through the pool area later and saw my sister, she told me to pee on it because urine neutralizes jellyfish stings. So I did and it felt way better.
