This is not 100% correct, but it's close enough. Post edits of this, because you 
probably have a better ear than I do.

Ab (xx1114@1)                          
Sometimes I can be perfectly sweet
          Bbm (x13321@1)Got this sugary me stuffed in my sleeve
       Cm (x3101x@1)And I talk of ponies and rainbows and things
         C# (x43121@1)And I'm just who you want me to be
          Ab (xx1114@1)But like most creatures down here on the ground
     Bbm (x13321@1)I'm composed of the elements moving around
       Cm (x3101x@1) And I grow and change and I shift and I switch
        C# (x43121@1)And it turns out I'm actually kind of a bitch
     Eb (x43121@3)But that only happens when I get provoked
         C# (x43121@1)By some piece of shit asshole we all sadly know
       Eb (x43121@3)And I sit and I write while reminding you all
      C# (x43121@1)That mean songs are still better than going postal
 
                   Ab (xx1114@1)And that guy's an asshole

                Ab (xx1114@1)So sing it out with me
                 Cm (x3101x@1)And then let it go

C# (x43121@1)Asshole
Bbm (x13321@1)Asshole

I see I've surprised you with some of my words
 And I know that surprises, while fun, still can hurt
 And I hate to think that I ruined the day
 Of the dick and the queen of the high horse parade
 But I'm sick and tired of your poisonous ways
 Your toxin wasting perfectly good space
 And I say what I think
 'Cause it's more economic than drugs or a drink

That guy's an asshole
 That girl's a bitch
 Baby it's natural
 No gettin' away from it
 So sing it out with me
 And then let it go
 Fuck that guy he's just an asshole
 
Ab (xx1114@1)And I won't let him in
Cm (x3101x@1)        C# (x43121@1)Under my skin
C# (x43121@1)                      Eb (x43121@3)You're a sad sack of shit
Eb (x43121@3)            Ab (xx1114@1)That's pathetic
Ab (xx1114@1)              
 Just a festering sore
Cm (x3101x@1)                C# (x43121@1)         
 Who will never be more than that
C# (x43121@1)            Eb/B  Eb (x43121@3)   
 If I don't let it

And that guy's an asshole
 That girl's a bitch
 Baby it's natural
 No gettin' away from it
 So sing it out with me
 And then let it go
 Fuck that guy he's just an asshole

That guy's an asshole
 That girl's a bitch
 Baby it's natural
 No gettin' away from it
 So sing it out with me
 And then let it go
 Fuck that guy he's just an asshole
