i got five on it

You're saying you're taking your cut of the weed, like you're the king of the stash and you're gonna get your quarter of the twenty. It also means you're part of the chaos and you're not getting screwed over.

You're saying you're gonna bet five bucks on a bag of weed like you're a gambling fool and you're ready to lose your cash.

This is what Luniz said when they were rapping about weed and money in the 90s. It means you're getting your five bucks on that sack, that bottle, or that big blunt.

You're bragging because you aced that AP test, and you're saying you're gonna take five bucks from someone else because you're that good.

You're saying you're gonna pay five bucks for that junk, and you're not even sure if it's worth it, but you're gonna do it anyway.

You're saying you're in charge, you're on top, and you're the boss of that situation. You're holding it down like a king.

This is a reference to Luniz's song from 1995, and it means everyone's throwing down five bucks to get the weed, and you're part of that deal.
