What is the definition of Define Sesquipedalianism01?

"Defining 'define sesquipedalianism01' is like trying to explain the difference between a pebble and a mountain, but with a side of existential dread. It's the act of labeling something as 'esquipedalian' when it's so unnecessarily long and verbose, it feels like a marathon of existential angst. Imagine if someone tried to define it by listing every single word, then doubling it up for dramatic effect. That's a sesquipedalian definition!"
