The verse goes like this, repeatedly:
E------------------------------------------------|
B------------------------------------------------|
G-------------------------2-2-2-2----------------|
D---------1-1-1-1-4-4-4-4------------------------|
A-3-3-3-3----------------------------------------|
E------------------------------------------------|
[ Tab from: http://www.guitaretab.com/b/bratmobile/278517.html ]
Chorus:
E--------------------|
B--------------------|
G--------------------|
D---2-2-2-0-0-0-0-0--|
A--------------------|
E--------------------|
And that's repeated a couple times before the end of the chorus which is this:
E------------------------------------------------|
B------------------------------------------------|
G------------------------------------------------|
D------------------------------------------------|
A--4-4-4-4-4-4-4-4-------------------------------|
E------------------------------------------------|
And that's basically it.
