A public spelling error found in a document you've already written and published. Embarrassment is increased in an error that cannot be edited once published.
Shame is proportionally equal to the size of the reading audience. Additional humiliation--when the person who finds your error is your boss. (Extra points for finding a spublic error in his/her comments to you. Extra, extra points for not pointing it out...)
It wasn't until the blogger hit "send" on his web site definition of Burning Envy that he found he'd committed a spublic error. Would he be able to edit it...? Tune in next episode to find out...
