Yeah this is where it starts getting tricky. If taken at face value its a song about a man cheating behind his 'lovers back' to get another woman pregnant so his legacy lives on. BUT the Roots rarely write lyrics to be taken at face value. The opening lyrics
'She wants neo soul cause hip hop is old. She don't want no rock'n roll. She want platinum, ice and gold' is setting up the analogy of the music industry being the woman in question. So
'I only want to fertilize another behind my lover's back. I sit and watch it grow standin' where I'm at ' is The Roots saying they dont want to stick to traditional Hip-Hop and instead want to venture into other genres, merge them, then watch where that takes them musically.
I could go on but lets face it, a 10-year old wont be looking that deep at the lyrics
