What does ride like a 36 mean?

assuming you are referencing "like a g6", the line is:

Sippin sizzurp in my ride, like Three 6

"three 6" being three 6 mafia, the group

This person was referencing like 3-6, meaning as stated. Ride like Three 6. Also known as Three 6 Mafia or triple 6. This rap group created a song which mentioned in the lyrics, sippin on some sizzurp or purple drink as some may know it. Meaning they were drinking and driving or drinking while in a car.

The Far East song like a g6 features these lyrics in similar fashion. Fly like a g6 can be interpreted as either something really cool or they are getting really high.
