chillin, make it 'chi dubs from the feet ubs' to mean all out complete chillin

Comes from the word "chill". If you seperate the beginning and end of the word, you get chi-ll. The "chi" at the beginning is obviously where the chi of 'chi dubs' comes from. Then, you have the "-ll" end of the word "chill" since it is a double l, you just abbreviate this and simply call it dubs, a shortened verious of double. Combine the two and you get Chi-dubs.
