first time i saw the word chumpie was in the Double XX Posse liner notes for Put Ya Boots On

I was like wtf they say that at?

This 90s rapper out in Cali Erule used it in the classic 'Listen Up'

But as you can tell from the flow he was highly NY influenced

Spent a lot of my younger years in LA, I didn't like that snap shit either. The majority of people used the hand slap / fist bump combo before I left
