fake words - hate'm

I hear enough of these "words" that I need an outlet for my frustration.
I'm not a spelling genius by any means. In my first spelling bee I got the word "buy" incorrect - spelled it "by" vs "buy".
Even though, here is my list:

"Heighth" vs "Height"
"Incidences" vs "Incident"... Incidences may be a word - but I don't think it is meant as the multiple of Incident.
"Acrossed" vs "Across"

Also, folks around here like to say, "I have THE diarrhea", vs "I have diarrhea".

Maybe its a NE Wisconsin thing....
OK, I'm off of my soap box.
