- Ear Worm: It's Lime Lime Time, Li-i-i-ime Time...
- Memetic Badass: Inbetween making fun of him, Retsupurae sort of play him up as some kind of combination of Rocky and Daniel-san.Slowbeef: What the hell was that?Diabetus: I don't know, but Billy kicks ass.Slowbeef: It's hard not to like Billy.
- Memetic Mutation: His comment about McDonald's, and the Retsupurae of it; the implication is that he gets fast food for Christmas.
- BILLY TRIES SO HARD!
- Narm Charm: Goes hand-to-hand with Adorkable on the main page. His over-the-top Nice Guy persona could come across as ridiculous, yet he's legitimately popular because of it.
- Tear Jerker: The above Crowning Moments of Heartwarming.
- The Woobie: BillyMC is this to EVERYONE who watched the Retsupurae commentaries of his Mario LPs, thanks to the hilarious but oh-so-very-sad backstory they gave him.
YMMV / BillyMC
