Well, this is a 2 person account, so lets just use Rose: and Shadow: k?
Rose:Really? I wanted to be Rainbow!
Shadow: Too bad, you're rose. :P 
Rose: I was just kidding! Sheesh. Anyway, we're bffs irl who decided to make our own account together.
Shadow: D: i wanted to say that! Ok, so our other single person or whatever accounts are rosez4ever and Shadowlight3.
Rose: Darn you. We also don't cuss, or at least I don't.
Shadow: I don't, and we are both anime luvers ^-^ and -
Rose:DEM YOUTUBERS
Shadow: Duuuun't (Don't) do daaat!
Rose: You mean,"Don't do dis."
Shadow: nope, and wow this must be the most boring bio ever. PINK FLUFFY UNICORNS DANCING ON RAINBOWS!!! RUB SOME BACON ON IT! (Those are both references)
Rose: SLAP THAT FOLLOW BUTTON WITH YOUR FOREHEAD!! (another reference)
Shadow: well, this was a long odd about me so.... feeeeesh! (fish- a reference again)
Rose: Bye. I'm tired so I'll go to sleep....zzzzzz
Shadow:...well, we woke up an hour ago... lolz....zzzzz....
Rose: Lol, I almost typed Rosez. If I ever met Deadlox, or Ty, I would shout #ROSELOX and tackle him to the ground. (Seeing as I'm thirteen, that would be near impossible.) If Shadow was with me, and we met BajanCanadian, I would shout #ShadowCanadian and embarrass Shadow. That would be hilarious!
