"Fluorescent Adolescent" lyrics

You used to get it in your fishnets
Now you only get it in your night dress
Discarded all the naughty nights for niceness
Landed in a very common crisis
Everything's in order in a black hole
Nothing seems as pretty as the past though
That Bloody Mary's lacking in Tabasco
Remember when he used to be a rascal?

From these lyrics I infer that a girl used to sleep around a little bit and is now more faithful, the words 'now you only get it in your night dress' suggest she is only sleeping with people at night, in her bed which is the more consertavie view this act and shows that she has changed and is now with one person who is good.

Chorus 
Oh that boy's a slag
The best you ever had
The best you ever had is just a memory
And those dreams weren't as daft as they seem
Not as daft as they seem,
My love, when you dream them up...

This is talking about how the rough boy she onced loved is no longer a part of her life but how she reflects back and enjoys the memories of them together.

Flicking through a little book of sex tips
Remember when the boys were all electric?
Now when she tells she's gonna get it
I'm guessing that she'd rather just forget it
Clinging to not getting sentimental
Said she wasn't going but she went still
Likes her gentlemen not to be gentle
Was it a Mecca dauber or a betting pencil?

This again talks about how she used to sleep around and be a different person to who she is now. 'clinging to not getting sentimental' shows that she never wanted to get feelings for anyone and not have anything serious. 'Likes her gentlemen not to be gentle' is another reference to sleeping with people.

Chorus

Oh, Flo, where did you go?
Where did you go?
Where did you go? Whoa.

This is representing how she left and that she is a different person and in a different place. It could have a very literal meaning, in the sense that she dissapeared or a more metophorical meaning in terms of where did your old personality and self go.

[2x]
Falling about
You took a left off Last Laugh Lane
You just sounded it out
You're not coming back again.

This shows how shes's left and doesn't have an intention of returing 

Chorus
