The Angry Birds theme comes from Rovio's Angry Birds, the mobile game that became a huge hit in the early 2010s. Low quality versions of the track spread through meme edits, reposted gameplay clips and nostalgic social posts because the melody is easy to recognize even when heavily compressed. It is still used when creators want a quick callback to early smartphone gaming, especially in jokes about simple games, childhood memories or chaotic physics-based fails.
