EXAMPLES:
I'll bring along MY AR-15 and BLOW you to Smithereens!!

It's GREAT to see that the school shooting are NOW extending into Colleges and Universities!! I LOVE this story!! And I'd LOVE it if the shooter gets away with it and is NEVER apprehended!!

And in response to a poster named Steve:

Little ********* Stevey, YOU have just signed YOU OWN DEATH WARRANT!! Also, I WILL decapitate your head and keep it as a souvenir!!
