Yay is a fandom-wide

Fluttershy cheers

meme concerning Fluttershy's 'feeble' cheering on of Rainbow Dash in the episode Sonic Rainboom.


In the episode Sonic Rainboom, Rainbow Dash was tutoring Fluttershy on cheering for her for the Young Fliers Competition. She began with teaching Fluttershy the Elements of a Good Cheer (loss of control, screaming and hollering, and most importantly, passion), and then asked her to prove her worth and show her a good cheer. However, being Fluttershy, her cheers were quiet, soft, gentle, adorable etc. (yay is written in the lower case to emphasize this). Dash told her to retry a few times, but to no avail. On her last attempt, she took in a huge lungful of air, and then released it in an earth-shattering "yay". And by earth-shattering, we mean nothing-shattering.
