Including Meatball Parade specifically was definitely me meming - specifically, a lot of the MMO specific comedy was inspired by the misadventures of Drakanous, GoldenTot, and their free company NEST in FF14 (links frequently NSFW). I thought you meant a sound effect.
Fun fact: I actually wanted to ask Drak to voice Hikaru, before I realized that I should probably offer Hikaru's voice to someone else for reasons that aren't in the game yet.
