Has no one definition and can chameleon as any part of speech, however it functions best as a verb. It may be be used in any context at any time positive or negative. It is like the blank spaces on mad libs in that it has the unique ability to let the listener apply whatever they are feeling at any given time. The word is also able to envelop the rest of one's sentence like a warm blanket around you on a cold snowy day. It is like snorting a dash of cocaine before your final exams or eating cinnamon rolls fresh from the oven. It is simply just everything.
