Coach describes opening the sea glow and figuratively applying it to himself to help restore his soul. He applies the sea glow deep into his core, explaining why he would place the sea glow past his heel, knees, tongue and beyond his the welts of childhood whippings. Also, the heel, tongue and welt are all parts of a typical shoe.

He’s saying that he isn’t perfect and has done some immoral things in the past. When a the sole of a shoe is dirty, sea glow is used to help restore it similar to how Coach would like to restore his own soul.

After drinking some Nuvo, Coach is a little tipsy and its clear from hearing what comes out of his mouth

Coach is driving around with a few of his friends

He’s shouting out his friend Gambino (Not to be confused with Childish Gambino) who is of Hispanic descent.

(Coach The Don, ObiWanSan & EZITO) = ISH whose flow is consistently great http://lockerz.com/s/174477949

He always has it his way similar to the title of the movie he’s referring to “Carlito’s Way”

He’s saying though he has the determination and drive to succeed he cannot literally go anywhere (Largo, Maryland) based on that and wearing Khaki shorts (Cargo shorts) can’t make his car go, another demonstration of Coach’s wordplay.

Coach demonstrates his wordplay saying he can’t leave beats (Or Instrumentals) alone, the word alone is a play on words similar to “A loan” which is what Wells Fargo would leave to someone in need of money.

Coach is saying he sparks the track the same way you would a Marlboro
