lets handle them one at a time, now people must understand that all nicks are not suitable for analysis by the pir. some are
in this case krooklynite is a great one..so lets assess the nick
krook- comes from crook
there is some hint towards brookyln
thus krooklyn..
and thus krooklynite as someone who is from krooklyn..i.e.e some gangsta G style version of a brooklynite.
I also see the hints of kryptonite in the ‘nite’ part of the nick.
so not only is it a gangsta native of brooklyn but someone who can destroy superman..or in GS;s case our charba version i.e. supermunna..
