A term originating from the popular phrase "Sure, Jan," it is a nickname given to someone you know is a liar. It can also be yelled at someone sporadically during a very important Twitter debate, or when some autist you know is obviously lying.
Tl;dr, Jan is a liar.
You can also use it as a nickname for obnoxious valley girls nobody likes, similar to Karen, but 16.

Get the Jan & Julmug. Doesn’t have time to read every supposedly creative “individual” definition of names. He still posts his own though... what a hypocrite.
