The commonly used word for the strongest (most researched) nuclear war head that can be produced in the 2004 video game Super Powers 2, designed by GolemLabs. The word originates from a player's name who is not known to be skilled at video games. The MBBC is also called a "Marie's Big Black Cock" due to provocative the shape and size of the missile.
I just launched 100 MBBC's at Russia, good thing their stability was already 10%!
