A block monster is the toughest guy
on the block. He can be a bully but he doesn't have to be. He's the guy who runs his hands the most and wins or is willing to run a fade at almost any given time. A block monster is more about
throwing hands one on one or in a group and stomping people out than
shooting guns. If they sucker punch some one at a party they usually don't run off. They'll finish the fight or if they knocked the dude out, they'll stay and laugh about it.
A feature of being a block monster is that they have a reputation for fighting and the people who know them, even people close to them, fear them. They can be big tall muscular dudes but they don't have to be. They usually have street legends about them either taking or giving brutal beatings involving multiple opponents. Or tall tales about going overboard with extreme violence. It's always good to remember they aren't bulletproof though.
Deebo from Friday is the archetypal example of a block monster.
Damn dude, that block monster Deebo
ran into a couple dudes at
the gas station who owed him money so he laid both them out, took their bicycle, laid it across them and jumped on it.
