The good ol days of middle and high school. A time where if you did something embarassing your peers would never shut up about it and bring it up every time. This is ingrained in our heads and follows us into adulthood. Imagine doing something embarrassing during a ms presentation. Now imagine doing it in college. The results are the middle school kids would laugh and bring it up hen they want to make fun of you. In college people are mature enough and would forget about it the next day because they're too focused on their own problems. Just understand that middle and high school kids are assholes and like adults dont care about you either but use embarrassing moments or flaws you have as an excuse to make fun of you. In actuality once you're an adult and are out there on your own, if you do something embarrassing or get rejected it'll be ok
