a massive nigga sandwich is a sandwich an individual can buy for less than $10 that is literally the size of a humanbaby. (not to be confused with a big nigga sandwich though.)
An insecure man who relies on a girl too much and emotionally traps her. Usually threatens her with suicide if she has thoughts of leaving him. Claims he has anxiety when they are separated. In Reality the man just has no qualities that make women want to stay so he must pretend to be all vulnerable.
