'looseo' and also 'theirso' when people confuse loose/lose and their/there/they're
From Daring Fireball: Itso: <p>QUOTE</p> <blockquote> A neologism for your consideration: itso — noun, pl. itsos : typographical error involving the use of it’s for its, or vice-versa. You have an itso in the second paragraph. </blockquote> <p>END QUOTE</p>
