look up any word, like yeet:
adj. More polite abbreviation for "fucking huge." Something that is much larger than its normal-sized counterpart and as a result, often out of proportion and much less pleasant to experience.
"Did you see the fa huge inflatable gorilla on the roof of that car dealership?"

"That baby could be cute, but it has a fa huge head!"

"I would have gotten the free coffee, but there was a fa huge line, so I bailed."
