Sega is a term that white people can call each other since its the white mans nigga.
Dude is on the street sees his home boy he goes up to him so he goes wut up nigga.
So since i'm white I can't say Nigga. If u have ever played Sega genesis all the games go Seggggaaa if u go N****A it sounds the same. So sega is the white mans n***a.
I see my man on the street I go yo wut up SEEEGGGAAA.
