I want you to know one thing
You ain't getting an engagement ring, yeah
So if you want to keep being with me
Oh, you've got to give me just a little, little more s***e
Stop chasing me around all over the place
And checking all the comments on d*** Myspace
And acting like a fricking nut
Why can't you trust me baby?
Why can't you trust me baby?
So I did a little blow, get off my back
It's not like I'm smoking crack
Why can't you trust me baby?
I want to tell you just one thing more
Don't treat me like a dirty man w****, yeah
'Cause I can walk right out your Mum's front door
Oh, you better treat me with a little, a little respect
Before I go Chris Brown and punch you in the neck
Keep your insecurities at f****** check
Before I f*** all your ugly friends, yeah
Why can't you trust me baby?
Why can't you trust me baby?
I must have caught something from the toilet seat
You know that I would never cheat
Why can't you trust me baby?
Why can't you trust me baby?
If you think I'll mess around then get a grip
Or you're gonna get a big fat lip
I tell you everything I do
Is always gonna be for you
But you never hear a word
You treat me like a fricking t***
Just like a big, juicy t***, yeah, yeah
You better open up your eyes and shut your trap
I ain't putting up with anymore of your c***
Stop threatening the b****** on my Facebook page
Or I'm gonna rip your head off in a cocaine rage
Why you gotta check my prison history?
Baby, why can't we just let it be a mystery?
Besides, everybody knows it was you
That blew Justin Bieber at the petting zoo
Why can't you trust me baby?
Why can't you trust me baby?
I wrote a little song so you understand
I don't cheat like the rest of the band
Why can't you trust me baby?
Why can't you trust me baby?
Our love is fragile like a piece of glass
Don't make me drop your big, fat a**
You ain't getting an engagement ring, yeah
So if you want to keep being with me
Oh, you've got to give me just a little, little more s***e
