Garen is a long-running champion in League of Legends, famous for waiting in bushes and then charging out with his spinning attack, which makes facechecking against him a classic mistake for new and experienced players alike. The 'wild appears' wording borrows the familiar encounter format from Pokemon, where a wild creature suddenly shows up, and League players adapted it into a running joke for ambushes. Clips using this sound spread through gameplay montages and short-form videos, where the reveal itself is the joke, and it remains popular because the bush ambush never stops happening in real matches.
