Pinkie Pie is the hyperactive party pony from My Little Pony Friendship Is Magic, the animated series that launched in 2010 and built a large online fandom. Voiced by Andrea Libman, who also voices Fluttershy, the character became a favourite for short reaction clips because her lines are expressive and easy to recognise out of context. This whatcha doin moment circulated on soundboards as a quick prank and check in sound, shared in edits where a cheerful interruption is funnier than a serious question.
