I can not fucking believe that someone would get butthurt over something that was said online and then take the opportunity to walk upto a person and talk shit to them. You know who you are dude. That's fucked up though for real. This is the internet, not a fucking battleground. It's alllll fun and games. You should be careful though, because you never know what that other person might be capable off. Shit, I bet we even have an undercover hiding behind a screen name.

Cliff notes:
When someone talks shit online, talk shit back.
Don't confront people over what was said IN person.
