I'll be pretty blunt here: Pil was sleeping one day, thinking about how comfortable his pillow was then he said BLAMO (in all caps of course) logged onto Minecraft creating pilberry to follow in the berry tribe whilst paying homage to their pillow. Whereas with her discord account, the word pillow was available so he ditched the berries for his one true love. The pillow.
once upon a time a falcon pooped on your head and you shouted at it "YOU FALCO" then people started saying "Thats the kid that shouted falco at a falcon!" so that's how you got your name
you were crushed by a arch and you became one but when the ign arch wasn't available, you became arxh, but that wasn't available and neither was arxh_ so you became arxh__ (im a he lol)
once you were in a small skyblock co-op and changed your name to MINICOOP, but then the coop disbanded so you went to a bar to get drunk since you were sad, and bar was so incredibly small, so you changed your name to m1n1bar
really? you quite like hoes, so you wanted your name to be related to them, and you chose 2 random letters, z and o, to go on the end because why not.
You had a sleepover and wanted to do a pillow fight, so you shouted, "Pill- OW" and then someone whacked you in the face with a pillow.
Your name is Kai, and you don’t have an iPhone but you wanted one so for fun you named yourself iKaai, the extra a was a typo
