Aye look, I took my rap money and I went and bought some kilo(s)
4th quarter, tie game, and one for the free throw

from Meek Mill – Banned From TV Lyrics on Rap Genius

Meaning

The money he got from rapping when starting out he went and got some drugs to sell.
4th quarter means it’s ¼ of the kilo left. When it’s crunch time he will break even (tie game) plus get extra for profit (and one). Drugs to basketball references.
