why did you lie to me
you said you were clean
but i know that your dirty
it's just so simple to tell the truth
i don't have time to listen to you

it's just your so...

so clean up your act
get it together
we're on the wrong track
and nothings getting any better

i know all about you
or at least what i think i do
i know that your dirty

so don't get bitchy at me
cuz i know the truth and i'm telling everybody
its just so simple to not agree
have your own opinion and you can be slutty

[repeat chorus]

your dirty you've been with everybody that i know
it's cool if you're a guy if your a girl it makes you a ho
your dirty you've been with everybody that i know
i'm sorry your life isn't 90210

[repeat chorus]

D.I.R.T.Y. you're dirty
