Sometimes known as MP. A penis that when erect is longer than 9" and has a circumference of no less than 7" (diameter of slightly more than 2"). Prolonged sexual intercourse with such an MP will likely cause vagina pain that lasts at least a week. This is not to be confused with miniscule penis, as it is the polar opposite.
Ruby: So, how was your night last night?

Candy: Great, but my vagina hurts because I had sex with a monster penis. I can't even sit down, laugh, or sneeze without discomfort.

Ruby: I hate when that happens. Damn, men and their MPs.
