She's Cheer captain, and I'm On the Bleacher. Bleach...er!

I listen to the raido Hot 99.5 during driving in my car, and I hear same popupar songs more than 3 time a day while driving because Hot 99.5 always focuses on the best popular songs.

So I nowaday  know pop song and sometimes I am able to hum to my self little bit.
The most joyful popsong  for me is "You belong to me" song by Taylor Swift.
In the song, I heard "She's Cheer captain, and I'm On the Bleacher".
I know what the cheer captain is... but On the bleacher??
I know bleach... Bleach is making something get paler or white.
So first time when I heard  the lyric  "on the bleacher", I could catch the meaning.
Now I knew it.  Long bench for spectators.
The expression to compare popular girl and common girl is funny.

In korea, we usually don't say likt that because cheer girls are not common in high school.

How can we say about the popularity.  I can't think .

Maybe we don't have...

Anyway, were you Cheer Captain ? or on the bleacher?
