(noun) a subdued thrumming in the head that is more unsettling than uncomfortable, and does not
hurt so much as just
feels strange, not at the level of a headache, something lighter, usually induced by substance abuse or an almost-hangover therefrom, but potentially resulting from
anything, or nothing, for all you know.
