When someone overuses a thesaurus in an essay or speech to make themselves sound smarter. However, by replacing small words with obscure words they don't really understand, it just makes them sound pretentious and stupid.
But, especially within hours of a tragedy unfolding, journalists and pundits should not manufacture a blood libel that serves only to incite the very hatred and violence they purport to condemn.
Blood libel? Purport? Looks like Sarah Palin suffers from thesaurusitis.
