He can pass for white, he's kinda a sex icon to white girls.
Also his team at "Tha Lights Global" is one of best teams in all of music right now when it's come to viral guerrilla marketing.
Most of the memes and internet discussions about him come from his team planting them.
Also, kids honestly like his music. I think he's trash and is recycling old "EA Sportcenter/Wilt Chamberlain" Gucci Mane, but to a lot of kids (like my little brother) his album is their generation's "Flockaveli", and a lot of them weren't old enough to even know the sound that he's copying.
