Flash Sentry and Trixie Lulamoon are both characters from My Little Pony Friendship is Magic, the animated series that began in 2010. Trixie is known as a boastful traveling magician unicorn, while Flash Sentry is a royal guard pegasus introduced as a calm, polite character. Short voice clips of the two have circulated for years inside the fandom and on soundboards, where fans isolate dry one-word lines and reuse them outside their original scenes as quick reactions for jokes, edits, and everyday dismissive moments.
