Revenge is a dish best served cold, with a healthy seasoning of spite and pettiness. Sure it might not be the most mature way to handle an enemy, but it's definitely the most entertaining.
These betrayed people could not wait for karma to do its job, so they took matters into their own hands. Now they're on Reddit sharing the prettiest way they have ever gotten revenge on someone. Do not try these at home.
The replies will make you laugh, cheer, and/or cringe.
