 You used to talk like you were dangerous
 Tell me to behave 'coz I don’t know who you are
 I must admit, you do amaze me
 But girl, that's how you played me
 to believe your every word
 Then I mix it up (wow)
 And you're mad
 Then I bring that one thing up and that's that,you're done
 Then you act like I’m contagious
 ‘Specially when you're raging or goin’ through my phone
 Why you gotta be so mean? (So mean)
 Why you gotta keep on doin’ dirt on me
 You're mean, so mean (so mean) to me
 Why you gotta, why you gotta
 hurt me like no one else?
 Is it 'cause you know me so damn well?
 Why you gotta be so mean to me?
 I used to treat you like an angel
 Kiss over the table
 And sing, ‘I Want To Hold Your Hand’
 Never knew you liked The Beatles
 Guess were just two people
 Who wanna fall in love
 But then I get ****** up (oops)
 And you're mad
 Can I bring the one thing up and that's that
 you're done?
 Baby, what you so afraid of?
 Think I would've stayed if
 I want somebody else?
 Why you gotta be so mean? (So mean)
 Why you gotta keep on doin' dirt on me
 You're mean, so mean (so mean) to me
 Why you gotta, why you gotta
 hurt me like no one else?
 Is it 'cause you know me so damn well?
 Why you gotta be so mean to me?
 (So mean to me)
 You ignore every call I make
 When I text, you say, ‘I’m busy, babe’
 You say things that I would never say to you
 (Oh)
 When we go out on a Friday night
 And all you do is talk to other guys
 Tell me, honestly
 Does that seem right to you?
 (No, it doesn't seem right to me)
 Why you gotta be so mean?
 (Why you gotta be?)
 Why you gotta keep on doin dirt on me
 You're mean, so mean (so mean) to me
 Why you gotta, why you gotta
 hurt me like no one else?
 Is it ‘coz you know me so damn well?
 Why you gotta be so mean (so mean) to me?
 Why you gotta, why you gotta be
 so mean to me?
