The growl is tied to the Carolina Panthers of the NFL, where a roaring panther sound is used in stadium as a cue for first downs and touchdowns. The team identity is built around the panther, so the sound reinforces that branding every time the offence makes progress. Clips of the cue have spread online among football fans and editors who reuse stadium sounds outside the game itself. It remains popular as a short, recognisable team sting and as a general big cat growl for sports montages and memes.
