Seen lately on a clothing forum:
"I just drape them over a chair or put them on a hangar." That one is spreading far and wide like a plague. Whatever that fellow is putting on a "hangar" must be huge!

Burgandy instead of burgundy is incorrect, but very popular nonetheless. Even ebay gets that one wrong in their listing templates.
Verbage instead of verbiage
Lavendar instead of lavender
