(verb.) the perpetual bonding of black men over ignorant or trivial things (i.e. living in the same apartment complex/projects, having the same Air Jordans, wearing the same color, have the same tattoos, wearing the same doo-rags, ect.) unlike the bonds between friends and family which are mutually beneficial, bonds created by niggasynthesis usually end up with participants having "caps busted in dey asses"
EX: gangs, crews, bruthas, ect.
a few well known examples of "niggasynthesis" would be the bloods and the crips
