I seriously don't get why some people here are having a hard time understanding the reasoning behind people's reactions.

I seriously don't.

because people in real life dont go apeshit crazy when an inside joke happens

it only happens on the internet

You can't ignore/exclude people from hearing an inside joke irl-- if they're within earshot, they will hear it.

On the internet, notably, an internet message board, it is VERY easy to keep your inside jokes inside. If you leak an inside joke/reference, that not everybody will get, onto a public message board, people will take that offensively, because you're taking the extra effort to post your inside joke/reference on a message board that is none the wiser about the subject.
