Paranoid Speller

A person so bad at spelling they can’t believe they actually spelled a word correctly. Symptoms of this paranoia are changing the spelling of a word in question to trigger the spell check for confirmation. Or alternately stopping everything and checking an obviously non-misspelled word at dictionary.com.

“Hey did John ever finish typing up that paper?”
“Yeah but it took him forever, he’s such a Paranoid Speller.”
