Oklahoma Borderline Acordes

	  Vince does a hammer on chord and I am not sure how to explain it...play a barre 
G then hammer on the 3rd string 4th fret, then 2nd, 3rd, and 4th string  
hammered onto the 5th fret. Axe, any clue how to better explain it? 
 
 
 
           G 
Well, it?s rainin? down in Houston, I got holes in both my shoes 
Baby put me on the street, she says I?m though with you 
She thinks I?m gonna miss her, so I?m gonna tell her that she?s wrong 
I?m goin? back to Oklahoma, boys, cause that?s where I belong 
 
Chorus: 
       C        G             C      G 
I need one good ride, I?ll be satisfied 
C          D           G 
Come on Oklahoma borderline 
      C        G               C           G 
If we rode all night, she?d be comin? into sight 
C         D             G 
Come on Oklahoma borderline 
 
Now I don?t need no Texas girl doggin? me around 
I may be an Okie, son, but I still been to town 
Well, these Oklahoma City girls, they always treat you right 
Tell momma and them I?m comin? home and I?m leavin? out tonight 
 
Chorus 
 
So with 2 bucks in my pocket and my thumb stuck in the wind 
When I cross Red River, boys, I won?t be back again 
Give me old back roads and truck stops and 18 wheels that whine 
And some good old boy to take me to that Oklahoma line 
 
Chorus
