The Variable Name Villain

The eternal struggle of reading someone else's code! Nothing screams "I'm a coding sociopath" quite like variables named 'x', 'y', 'z', and the legendary 'temp'. Future maintainers will spend more time deciphering your cryptic single-letter variable names than actually fixing bugs. It's basically leaving time bombs in your codebase. Clean code? Never heard of it! Bonus points if you name your class 'Mgr' and then wonder why nobody understands your "perfectly logical" architecture six months later. The true mark of a 10x developer is making sure nobody else can be productive with your code.
