Apathetic means feeling no interest or care about anything. An apathetic crowd, apathetic about politics, grown apathetic.
It is not the same as lazy or unhappy — apathy is the absence of caring, and it can be a symptom of depression or of exhaustion rather than a fault of character. Voter apathy is the commonest use. Note the a- meaning not, and the Greek pathos, feeling.
