Dis-knee to the groin

When one feels subjected to too many Disney movies

bad knee day

Similar to a bad hair day, but instead of having nasty looking hair, the victim has nasty looking knees. May result in dryness, stubble from shaving, rashes and/or birthmarks.

Most often used by women.

Wow, look at all that stubble. I'm sure having a bad knee day today!
