Portmanteau of whore and thesaurus.
A
person who arbitrarily laces their writing with high-register
words, usually but not necessarily with the assistane of a thesaurus, in a
way which is intended to impress the reader but does not actually add to the content or depth of the text.
"Hey, does anyone know a synonym of 'blah' that sounds more intellectual?" - Thewhoraus
"Does he think I'm that stupid? Replacing
words with thesaurus entries is the oldest
trick in the
book." - A thewhoraus's English teacher
