Very true, but if people don't know about it, then hear someone use it in a game, it can have a very harsh consequence.
i.e.
Like my child may be in the other room and hear the term from someone else online. Then use it at school in front of their friends and get in a lot of trouble.
"One kid screamed the term in my ear and I was forced to take off my headset, then my cousin, who is 10 years old, heard them scream it and started to repeat it. Not knowing what the "R" word meant, his mom tanned his hide. And it wasn't even his fault."
It's monkey see, monkey do. And I'm sure there are more instances that I'm unaware of.
It would be very hard to censor online MP. Even since the characters in Zombies say some pretty vile things.
I would consider making new catch phrases that the Characters say to replace the term in question.
Then perhaps the community would start to use the slang form the game they love in stead of the current inappropriate term.
Just my opinion though.
Let me know what you guys think.
