Quoting round3:" Kinda sounds to me like maybe he just thinks he is being "cool". The influences of video games, movies... ... [snip!] ... but I wouldn't immediately think he was really smurfed up I would just think he is 13 and growing up with bad influences."
It could be that, or maybe he didn't think of what he was saying before he said it.
When I was in 7th grade (around the 1 year anniversary of the Columbine high shooting).
A kid in one of our classes jokingly said, "Hey on such and such day, we should all come to school in trench coats." He said it out loud in front of the entire class, and we all told him that's not funny.
He wasn't an odd ball, and didn't shoot anyone up, or anything like that. Sometimes people say stupid smurf because they don't think before they speak.
