Oi, Doug, I use all sorts of words in my posts that I don't see others using. If you're going to make up non-dictionary definitions, here's one of mine:

PRETENTIOUS: of words designed to make you think (mistakenly) you look clever and super-educated but for which there are plenty of simple and common synonyms, e.g., "albeit" (pretentious and often misused); much better synonyms "though," "although." "Prior to" (pretentious); the synonym "before" works every time. "Relatable" (pretentious); plenty of synonyms which far more clearly express the intended meaning, such as "engaging," "sympathetic," "friendly," "collaborative," "approachable," "mutual understanding" (these especially with regard to people). Or get more colourful: "on the same page," "chimes with me."

Also worth avoiding: "end result"; "at the end of the day"; "in close proximity;" "I have to say...", "3 AM in the morning hundred hours."
