Moon Stone
"Moon Stone? More like bullshit." is a phrase from a romhack of Pokemon Blue known as the "Cock Version"; it contains a complete rewrite of the game's dialog to be as offensive and crude as possible. The statement is uttered by a visitor of the Pewter City museum who's standing in front of the Moon Stone exhibit. Upon talking to the NPC he calls the mysterious stones "bullshit" despite evidence of their existence literally being in front of him.
Although the playthrough of Cock Version had to be cancelled due to racist remarks within the game's character dialog the Moon Stone phrase has remained a standby of the community due to how hard it made Draco laugh. The phrase has its own dedicated trigger within Nightbot, !moonstone, which will prompt the bot to reply with the quote. The quote is also expanded upon when games of particularly frustrating or poor quality are played and the Moon Stone is replaced with some aspect of the game in question to call it bullshit.
