look up any word, like spook:
The feeling one gets at the beginning of each working week; also known as the 'Monday Feeling'.
"Man, everyone in the office is feeling a bit Mondayne!"
"You're right there!"

A mundane Monday.
So I arrived at work today, and I am staring at the same thing that I did last Friday. Actually the same thing I've been working on all month. It's definitely another Mondayne.
