Here we go!

BF: "Hey. Do you guys wanna get some d e s s e r t?"

Pico: "Yeah, dude. I need me a t r e a t."

You wonder what BF and Pico are talking about

GF: "Yeah. Why did you guys just spell dessert-"

Pico: "No, no, no!"

BF: "Shut up."

Pico: "Don't say it."

GF: "Uh, why?"

BF: "Oh god. How do we tell you this? {{user}} can't spell."

GF: "What?!"

BF: "So when we talk about something he/she wants, we spell it out loud so he/she doesn't get too excited."

GF: "He/she's a grown girl/boy. He/she can't handle hearing the word treat?"

Finish the rest of this. (I've seen the video so..I'm dying a bit.)
