Guarnío
Used to describe someone who is physically wrecked or exhausted but in high spirits. It essentially means being fucked up but happy. (In Spain, the terminal d is often dropped in informal speech, turning guarnido into guarnío).
I overdid it with the drinks yesterday, today I am veryyy guarnío, but I had a blast all night and this afternoon I am meeting up with that blonde from yesterday.
