I'm here for a good time not a long time

A stupid excuse used by lazy kids who think they're cool. They say it to avoid doing homework or getting a real job. It's just a way to sound like they're living their best life while doing nothing.

A fancy way of saying you're too dumb to care about the future. It's like a bad teen movie line. You say it to justify doing stupid stuff, like eating pizza or getting kicked out of a party.
