Quán Quân Pom-Pom!

You must specifically send Pom-pom stickers to 5 different friends.

Comes from the "You've Been Gnomed" meme. You've Been Gnomed is a computer animation of a gnome mythical creature named Noggin Clontith, who taunts the viewer at the end of the clip by saying "You've been gnomed!". People began using this as a way to troll their friends, sending the video link and claiming its something else, just to be surprised by Noggin. The way you get the achievement in game totally represents that, who would expect finding Pom Pom on the globe in Qlipoth Fort. - Credit: Kyrad
