We always called that German kid in class that we bullied 'Heckler'. Then he showed up with a 'Heckler' Koch 416
I'm not sure if I get the joke. Are you making fun of a shooting victim?
That's a joke. My friend called him Heckler Koch where I grew up and he got offended by it so I thought why not make this into a joke.
That's a clever joke, but it does make light of school shootings in general. More disturbed individuals may take this joke and re-enact it literally in their own schools. It's not right to encourage such suffering as a result.
