Big Bossing It means to be big boss personified, a man so
misunderstood and so badass, but damaged by past events and now driven by revenge
for the cause,
the person big bossing it does not care about anything or anyone anymore, realizing everyone hates him and also wants him in a system or in a grave, but he continues to fight for a better future (that he can never achieve)
the big boss-er will throw everyone away holding him back
the big boss-er is a force for those with no other recourse
the big boss-er does not take shit, from anyone or anything, for any reason, no matter the cost
