Don't forget, Scar likely was quickly losing his sanity, combined with his other issues he probably saw Mufasa's nickname as a terrible offence. Scar might still have a real name that means garbage and Mufasa was trying to make him feel better.

Also, we don't know what actually happened that day. Heck, maybe Scar doesn't remember everything all that clearly. Everyone interprets words differently, sometimes if you're in a bad mood you might hear gentle teasing as merciless mocking.
