An insult in the Percy Jackson or Heroes Of Olympus fandoms. Meaning being idiotic or ignorant. Mostly fangirls or fanboys will call you this. It is very offensive to fangirls or fanboys if called a mortal. Be prepared to be stabbed, smacked, or punched. (For some extra zing they might stab u with a pen)
Oh my gods dude, your such a mortal.

To get so incredibly drunk you only escape your mortality from alcoholic poisoning by pure luck. Probably originating somewhere north uk (or another country altogether). This term is usually used prior to going out drinking, and is followed by a failed effort or pretence of being incredibly drunk.
