A common misspelling of "their"

Often made by new generation kids who spend all their time slacking off in school, and using abbreviations on nearly any word concievable.

Or, by those who think "I before E except after C" is a rule in English.

The "correct" spelling of their according to one angry, lonely, and rude "college graduate" from Suffolk, Virginia that called the Suffolk Times news editor to correct him.
"The correct spelling is thier, not their. I went to college."
