Proper noun. Pronounced (Que-bee). Sort of like Rubix Cube but not.

1. A Vocaloid mascot for the Vocaloid Yohioloid whom is destined to become an internet meme, but sadly will never happen for he is not a meme.

Origin: High School of Mutual Memeing on Quotev.
"Cubi was totally an ordinary box thing. But everything changed when he was first accepted into meme school."

"Cubi wants to be the meme sempai, but does he have what it takes?"

"So Cubi went into the girl's bathroom, feeling no guilt at all b/c he's neither a mademoiselle or a dudefella."
