The Gladiators Boy in Long Pants Part Two

(My best attempt at interpretation);

I man no like how them man them a gwan
take mi name carry it to you girl
if you want love and don't know how to ask
write her a letter, explain it to her

You said ya man stood up like a boy
But he don’t know he’s bigger than you
You saying girl you carry mi name too
You saying girl girl you let out the secret

(Chorus 1)
Girl a say boy, oh ya, in the long pants
Ya girl a say boy, oh, hoo-hoo, in the long pants

(Chorus 2)
You have the AGE of a man
big belly also
But all you is is up a bed [or bet?] and a string
That’s why your friend keep laughing at you

(Chorus 1 repeated)
(Chorus 2 repeated)
