This has to be my most cringe-worthy typo or misspelling. Misuse there/their, where/were and I'll want to break out the red pen to correct it. Misuse lose and loose and the sword shall be mightier than the pen, so help me!

Lose - to miss from one's possession or from a customary or supposed place.

Loose - not rigidly fastened or securely attached.
