Don't use the word if you have to make one up.

Message Board Post from Anon (regarding the movie Borat):
"I found it slightly humorous, but then very offensive. I walked out! I'm not too old to appreciate humor and satirism. But this went over the line in my opinion. I just couldn't laugh and feel comfortable laughing. "

Personally, I am offended by your use of the word "satirism". But maybe that's just me. Also I prefer if you spell humor with a "u". humour. It's just prettier.
