Big M

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.“
