Fattus Maximus 

One who is massively overweight and uses gym equipment to watch Netflix on the treadmill.

Also sits around and eats KFC all day.

Dude 1:Dude, did you hear that the Reddit user u/GherkinP is a fattus maximus?
Dude 2: yeah, I heard he uses the treadmill to just watch Netflix.

Flattus Maximus 

Flattus Maximus is a red faced guitar god in the band GWAR. Flattus is the lead guitarist in GWAR. His outfit consists of two triceratops on his shoulders, a green cloth to cover his areas, his killer footwear, a red mask, and of course, his customized green (sometimes uses red) ESP LTD MH400 guitar.

Womb With a View and Bring Back the Bomb are great examples of Flattus Maximus shredding on guitar.
