Noun; an obese or very fat person. Not to be confused with the term Goiter, which is typically a protuberance from the neck or other areas. Also, Goiterous refers to a type of meal which will lead to one becoming a large, fatass person.

Can be used as a verb to describe a fat person while in their presence, yet not actually calling them obese to their face.

Used as an adjective to describe things that either make one look fat, or enhance ones current state of fatness.
"OMG, I just wolfed down a Big Mac, I feel Goiterous!"

"Holy shit! Check out that fatass chick, she is the epitome of Goiterous!"

That outfit is too tight, it makes you look Goiterous...
