The biological junk drawer: not plant, not animal, not fungus, just vibes and a nucleus.

means A protist is any eukaryotic organism — like an amoeba, algae, or paramecium — that doesn't fit neatly into the plant, animal, or fungus kingdoms.

from From Greek 'protistos,' meaning 'the very first' or 'primal,' a superlative of 'protos' (first). The term was coined in the 1800s to label these organisms as the earliest, simplest forms of life — the evolutionary starting point before biology got organized into tidier kingdoms.
