3Hunna comes from Chief Keef, the Chicago rapper who helped bring drill music to a mainstream audience in the early 2010s. The track appeared on his debut studio album Finally Rich in 2012 and became one of his best known songs, with the title referencing 300. Short excerpts later circulated on soundboards and in fan edits, where the distinctive beat and delivery made the clip easy to recognise out of context. It remains in use because that early drill sound still signals a specific era of internet rap culture.
