Im still a kid but in fourth grade i spelled forget on my DS
LOL I DID THE SAME THING. We were on a bus to Phillidelphia, and I changed my name to dragongirl and spelled forget in the chat, afterwards, I changed my name back to Paul and began to play Nintendogs. Shortly after nobody in the school was allowed to take DSs or phones on field trips.
I remember stuffing my sweatpants full of those troll dolls when I went to Walmart. No one noticed the bulging all over. I went home and my mom finally noticed, and got mad of course. We had to drive back and apologize. 
I just read this one, along with Socko's and Pixl's, it's the only one I lol'd hard at
