An alternative to the term Cyber Monday, Blue Monday is the Monday after Black Friday, when online retailers will be looking for their biggest sales from those who checked out products over the thanksgiving weekend, and will now be ordering them Monday at work.

Forget those long Black Friday lines, I'm going to order on Blue Monday!

When one has the Monday blues, it means they are tired and stressed to be back at work (or just be back to Monday in general). Everyone has a shared "ugh" state of being.
Do not ask me how I am. It is Monday. You KNOW I have the Monday blues.

I had a rough weekend and now I have the Monday blues. This SUCKS!
