Produce G's like sperm
Triple entendre: A “G” is a thousand dollars or a gangsta. They produce money the way sperm makes lil gangstas. The “G’s” is also referring to “gametes”. And third, G’s could also be jizz — it sounds like it and consists of sperm.
He could also be referring to the lucrative act of donating sperm. Some men make thousands of dollars — G’s — off of sperm donations.
