When one listens to Lindsey Stirling on repeat for so long that one's dreams are haunted by intense electric violin/Dubstep background music, resulting in one's sleep being constantly interrupted.
You: I'm so tired, brosephs. This has to stizzop.
Your Coworkers: What's going on, dawg?
You: I totally got Stirlinged again last night - woke up at least thrice.
Your Coworkers: Dayum... you really gotta stop listening to Lindsey on repeat at work, home slice.

Every official Stirlingite has suffered from the disease of Stirlingitis, unfortunately an incurable disease but no one's complained about it yet. Being in the Stirlingite family is a decision no one could every regret.
Random Stirlingite1: "Hey, thanks for the add... but do I know you?"
Random Stirlingite2: No, but you're a Stirlingite, so am I, we're already mutual friends!"
Random Stirlingite1: "OH! Great! KSLL Stirlingite!"
Stigginit is a portmanteau of the phrase "sticking it to the libs (liberals)." The word apparently originated on Fark.com as a way to mock the practice of some conservatives who engage in a practice not because of merit or self interest, but merely because the practice is opposed by a liberal, especially in those cases where the practice is clearly against one's self interest.
Those libs want to raise the minimum wage, and even though I work at McDonalds I'm going to vote Trump because Stigginit!
