The 'Hey Hey You You' Cat Dancing meme features an enthusiastic cat vibing to the iconic lyrics of Avril Lavigne's 'Girlfriend.' Gaining massive traction on TikTok and Reels, this template captures a specific brand of chaotic joy often used to represent a person's reaction to good news or a sudden burst of confidence. The meme typically uses a cutout of a cat performing a repetitive, rhythmic dance that syncs perfectly with the 'Hey! Hey! You! You!' hook. It has evolved into a go-to format for celebrating small victories, payday feelings, or simply showing off a playful mood to followers across social media.
