Splavacado was a re-occuring joke between Sky and MunchingBrotato in ["Minecraft Mini-Game: SPLEGG!"]
In the splegg game, Sky, Brotato, Seto, and xRpMx13 discovered that they all had eaten eggs earlier in the day. Sky made the comment that he had also eaten an avacado, to which Brotato replied, "Oh. Well then we're also going to have to play splavacado after this."
- A few days after the video, a Youtube channel called "Splavacado" was made in honor of Sky.
