When you seem to have lost all hair accessories and very badly need to keep your hair out of your face. When having a case of hair-tie desperation, the affected will use nearly any accessory and/or item in place of hair-ties or head bands. This sometimes works fir the affected and other times ends in a complete fashion disaster.
Girl One: Hey, where'd you get that head band? I''ve never seen one with that shape.
Girl Two: It's actually a neck-tie my mum bought for some random project she was working on. I had a major case of hair-tie desperation and it actually looks kind of cute.
Girl One: Nice.
