Definition:
A holiday in the United States made to celebrate our past presidents. (Including George W. Bush and Nixon)

History:
When the United States of America won the Revolutionary War in 1783 the People wanted George Washington to be King, but he just wanted to sit on his ass at his luxury estate in Virginia. So instead the People had to settle with him being President, and in their sadness the People decided to hold a birthday party every year for Washington. Politicians later in the 1990s the idiots who invented Political Correctness changed the name from Our King's Birthday to President's Day, and decided that would be a good reason to have 50% off sweaters at JC Penny's.
"Back in my day we walked barefoot through the snow to school. Uphill both ways! And President's Day didn't exist! We celebrated King George Washington's Birthday!"

"Don't miss our semi-annual President's Day Sale. All sweaters: 50% off!"

A holiday that has no real reason other than being an excuse for furniture and automotive dealers to have huge sales, and make Americans that don't know anything about their government feel stupid.
Example One: It's Presidents Day, so come on down and fork over alot of money for this used car...

Example Two:

Dumb Person: Hey, Happy Pres. Day, man!

Smart Person: Yeah...okay. Hey, do you know who the first five presidents were?

DP: Uh...Washington, Jefferson...Lincoln.

SP: Exactly.
