A Big M is a way to say “hardcore masochist“. The term is used to refer to a person (often a fictional character) who may be the type to get unusually happy when thinking about or receiving pain.
“Ah, he really likes hanging around with such a fierce girl. How does he deal with her? He’s either a silent badass or a Big M.“

Short for "Meel'd in the morning" which means to feel weak or unsure whether you are able to make it out of bed. You can identify when someone is Meel'd in the M when they have a raspy voice and eyes are not open to maximum capacity
