Guesstizaggerate
A combination of a guess, estimate, and exaggeration. An exaggerated guesstimate. Came to me as I was untangling my laptop cord and earbuds for what I guesstizaggerate is the one gabillionth time.
I guesstizaggerate that I've spent 10% of my life untangling cords. 51% of that on earbuds.
