Mafia City is a mobile mafia strategy game whose ads became a meme in the late 2010s for showing a low level crook rising to a level 100 boss. The format spread across YouTube and social media as That's How Mafia Works, with people recreating the upgrade ladder for games, school and everyday life. The ad music became shorthand for that transformation, so creators still use the short cue whenever a character gains status, confidence or power in a deliberately exaggerated way.
