I know it was embarrassing and this prank is very inappropriate and dangerous, but taking revenge isn't a good way :) you know one of my favorite quotes say "Weak people revenge. Strong people forgive. Intelligent people ignore". If you're planning to put an end to this, then I advice you to inform an adult/parents or your teacher, they take a better action than what you'll do. They can contact your mate's parents and inform them on what happened, their parents should be aware of what's happening too and be informed that what's going on is not good. An adult's action is much more wiser since they have more experience and have dealt with other people and with more situations, whereas your action might not be as wise as theirs and it might end up in a bigger problem which you'll regret later.
