Soulja Boy lyrical genius?

[Chorus:]
This right here is my swag
All the girls are on me, damn
Everybody pay attention
This right here is my pretty boy swag (ayeee)

Girls scream my name when I pretty boy swag

Get out the wayy

Girls on my heavy 'cause I look so sexy
Yellow diamond shawty in the club straight

Dick in the hips come and get in my car
You party with a star we take off and go to mars
Pretty boy take off in 5.4.3.2.1

No homo shawty but my chest is straight flexy
Tatted on my neck shawty said she choosey
She got big titties and a fat ass booty
Took her to my condo let that girl strip
Then she got naked then she pretty girl dip
Damn I like the way lil mamma shake that ass
She pretty girl dipsum while I pretty boy swag

[Chorus:]
This right here is my swag
All the girls are on me, damn
Everybody pay attention
This right here is my pretty boy swag
