A high holiday rivaling Christmas among military personnel. Used in reference to the period of time after porta-potties have been emptied during which one can maaturbate peacefully unencumbered by the smell of shit and urine.
Any day off that is planned in advance. These days can be used to run errands, visit friends with different work schedules than you or just lounging around the house in your robe.
These days are best utilized on Fridays and Monday's, however taking one on a Wednesday is a nice mid work week break.
Mike: I have a lot to do this coming Monday. I think I will take a blue robe day
Scott: ummm....ok? Isn't that like calling in sick?
Mike: yes, but I plan on getting a lot done tomorrow.
An expression often used by out-of-date ski bums and boarders describing an otherwise beautiful, blue and sunny day. The expression is entirely unrelated to spring or to bluebirds.
Carmela: "My relationship is causing me so much stress, I don't know what to do."
Emily: Maybe he's your blue butterfly; a rare experience that is only meant to be a lesson, not a forever.
Carmela: "What does that have to do with it?"
Emily: "It's National Blue Butterfly Day; do with that information as you will."
