My criteria compared to your career just isnt fair,
I'm a venerial disease like a menstrual, I bleed...
Through the pencil and leak on the sheet of the tablet in my mind,
Cause I don't write nothin cause I ain't got time..
so he's saying, like a venerial disease or like a menstrual (means period, I hope you know that) he bleeds through the pencil to write his lyrics in his mind, cuz he doesn't write shyt cuz he doesn't have any time...so he's leaking his words through the pencil in his mind like an std or period...get it?
