Here's another demo-song によって Placebo!!
I think its talking about a close situation to the song Every あなた and Every Me...

So,here あなた are...

It echoes in my brain
I didn't mean it
pulses through my veins
I didn't mean it
I'm the one to blame
I didn't mean it
did too much cocaine
I didn't mean it.

Slackerbitch, faghag, whore
looks real cute, her lips are sore
slackerbitch, faghag, whore
always comes back for more

Your memory will fade
I didn't mean it
you've always had it made
I didn't mean it
I know あなた feel betrayed
I didn't mean it
I just wanted to get laid
I didn't mean it

Slackerbitch, faghag, whore
looks real cute,...
