The intro lyrics are rather...random with some innuendo. Still, fun to listen because it's so...lively. Here are the lyrics that I've translated off of the A.F.K. fansub.

"Motteke! Sailor Fuku!" Lyrics
Around 3cm! Looks peachy doesn't it? Supah!
Old-fashioned uniform! Turn-off, ain't it? BOON!
Just work it! And do it!
Don't forget to catch and release yo!
I SAY! WHOO! I SAY! WHOO!
And throw in a DARLING! DARLING! PLEASE!

Time for talking! Something's coming! I love you so!
Oops! I screwed one upsie-up!
A nail biter! A steel beater! Gourmet eater!
Cut that out already!
Is the new girl popular or what? Since I'd call her normal girl.
Wowzers! Only for me? Firm noodles! Fill her up again!

DA-DA-DA-DA-DA!!!

(Random chatting over instrument)
OOH! Guess what!
My glasses...where are my glasses?
I've been playing the same fighting games lately.
If I don't have my glasses...

BON BON! Cheerleaders!
LET'S GET CHERRY PIE!
RAN RAN! Welcome party!
YOU'VE GOT A SENSATION!
HIGH! Leaving an impression! Scattering asteroids!
Crash and burned! Shockers!
Break into song! SING AND DANCE!

Take it! I'll still be laughing in the end!
Because it's a sailor uniform! Conclusion!
It's only Monday and I'm already blue. What to do?
I'd rather wear my summer clothes. So cute!

3-Piece uniform! That's a toughie to pick! YAN!
Just work it! YEAH! To the limit! YEAH!
MY DARLING DARLING PLEASE!
