Weekenditis 

What one who works a full-time job will catch at a certain point in the week where they are no longer willing to do work in anticipation to the upcoming weekend; similar to the more popular 'senioritis' often found in high schools.

On Thursday afternoon Stacy threw down her work and said "I'm done, I'm not doing anymore, I've got a severe case of weekenditis," as she strolled off to the break room for an undetermined amount of time.

Weekend-itis 

A sick day on either side of your normal days off causing your weekend to swell.

I came down with weekend-itis when Friday got in the way of my three day weekend.

weekendation 

A very short leisure trip taken on the weekend, sometimes over the course of a 3-day weekend when a holiday falls either on the preceding Friday or following Monday.

Our weekendation to the shore was so much fun but it was way too short. I can't wait to go back!
