Can 'floccinaucinihilipilification' be considered a real word? [closed]

Can 'floccinaucinihilipilification' still be considered a real word?

The only context that I have ever seen it used is as an example of one of the longest words in the English language.

Also how would you use it in a sentence?

Do we have to use literally in a context where estimating somethings value is being done, or can it be used more metaphorically where it is argued that something is meaningless (ie has no useful value (like arguing a word is useless)).

Also how would you use it in a sentence?

I once did use it in a sentence. I was negotiating a deal for the sale of some baseball cards. The buyer was concerned that the cards might be fake. Another person looked over the cards, but I knew he tended to consider cards fake even if they were 100% genuine. (Natural variation on older cards can make them look 'trimmed' but the machines those days made irregular cuts and not all cards were the same size.) He pronounced a T204 Ramly trimmed (and thus worthless). I demanded he cease his floccinaucinihilipilification. The buyer snorted soda out of his nose.

I consider it one of the greatest things I ever said. Better than when I told an extremely ugly woman who was talking about how much she loved nature that I considered this surprising considering that nature clearly hadn't returned the favor.

In its entry on floccinaucinihilipilification, Oxford Dictionaries notes that "the word is used chiefly as a curiosity."

(Note the largely contrived attempts at usage here.)
