Neologism is a somewhat common word in my native language (neologismo), it's a term I learnt in middle school during language classes, sorry if it sounds "pretentious" to you but it's a perfectly apt word to describe what I wanted.

"Small majority" is of a different kind, much more akin to weasel words. Hence: say what you mean, don't hide behind a neologism that tries to masquerade as something else.
