From my cousin who got it from my father (Sgt. Maj. USMC).

As we go marching and the band begins to pllllay,
You can hear the girls shouting the raggedy-ass Marines are on parade.
Eyes right, assholes tight, advance foreskins to the rear.
We're the boys who make the noise, we're always on the go,
We're the heroes of the night, but we'd rather drink than fight.
We're the raggedy-ass Marines on parade.
