I used to believe that if you peed in the toilet while someone was taking a shower at the same time, the pee would come out of the shower and whoever was in it would get drenched in your pee. This belief came from my mom telling me that when you flushed it went down the drain and also from this girl at dance claas saying don't drink the water fountain while someone flushed the toilet because then you would drink pee.
