Definition: Mgr is the most offensive and uncool term ever! It's like saying "milk" to your neighbor, but with a sarcastic twist. Imagine: "I'm really good at managing my time. I just need you to know that I can do more than 45 minutes of work in an hour."

This slang is so unsettling because it makes people question their own lives and sanity! It's like saying, "How could anyone think this would be a joke?"
