Verse: 

E                              C#   G# 
Now she's fucking with Brian's head 
E                           C# G# 
He's screaming let me go to bed 
E                             C# G# 
She tells him this is all for fun 
E                         C#  G# 
He's tired now of feeling dumb (?) 


[Refrão]
Am          Bm   
Lost in his head 
         Em                 Cbm 
And he's losing his fucking mind 
Am                Bm 
Losing all of his friends 
          Em                Cbm 
And she's taking all of his time 
Am                Bm 
Never leaving his sight 
        Em                 Cbm 
As she leads him through a day 
Am                     Bm 
Oo Wah oo she makes me gay 

verse 2: 

E                              C#   G# 
And now he's banging the same chick 
E                                  C#   G# 
Said girl right there she's in your head 
E                            C#   G# 
She keeps him up all day and night 
E                           C#   G# 
He's turning back on chiken fights (?!???) 


[Refrão]
Am          Bm   
Lost in his head 
         Em                 Cbm 
And he's losing his fucking mind 
Am                Bm 
Losing all of his friends 
          Em                Cbm 
And she's taking all of his time 
Am                Bm 
Never leaving his sight 
        Em                 Cbm 
As she leads him through a day 
Am                     Bm 
Oo Wah oo she makes me gay 

Bridge: 

I can't figure out the lead guitar part but the rhythm guitar just plays 
the verse over a few times.  

Verse: 
   
E                            C#   G# 
Hey Brian have you heard the news 
E                          C#        G# 
Hey Mike we gotta tell you something too 
E                               C#   G# 
The girl we loved has fooled us both 
E                            C#   G# 
And all she left us was this note 



Am          Bm   
Lost in our heads 
         Em                 Cbm 
And we're losing our fucking minds 
Am                Bm 
Losing all of our friends 
          Em                Cbm 
And she's taking all of our time 
Am                Bm 
Never leaving our sight 
        Em                 Cbm 
As she leads us through a day 
Am     Bm               Am           Bm 
Oo Wah oo she makes us gay ooooooooooooo 

Outro: 

Am     Bm               Em         Cbm 
Oo Wah oo she makes us gay ooooooooooo 
Am     Bm               Em         Cbm 
Oo Wah oo she makes us gay ooooooooooo 

(Repeat outro a few times)
