Rickey's spiel is a reference to IRL Blue Archive's debut race on Jan 21, 2023, where he finished fifth despite being the third favorite. It's also a variation on a Japanese copypasta meme which had Gokusen's Yankumi defending one of her students who faps to Blue Archive (the game, not the horse).

And yes, people were posting Yankumi-BlueArca copypasta snowclone memes all over the place on horse racing boards and social media.

Original copypasta (translated):

Kept you waiting, huh.

DON'T YOU GUYS DARE LAUGH!

He's been fapping away real hard in secret to Blue Archive every day!

Do you guys even fap to Blue Archive every day and cum?

If you don't then DON'T LAUGH!
