Lyric discussion by JustineByrrd 

Alright. let's put everything together without anyone's personal experiences influencing the interpretation:

Boy likes girl. Girl sings song about it.

For whatever reason, the girl likes it rough, or at least wants it rough. She wants to feel something strong and powerful, perhaps sort of like how many women have rape fantasies.

I really don't think the tissues are because she's crying, c'mon, she's fighting in this song!! She's having a good time - alone. She needs tissues... yeah, now you've got it.

This guy that likes her is soft, but she wants a fight to know it's real. She wants to be able to fight and be crazy and still be assured the guy loves her back and wants her enough to fight for her, with her. This guy, on the other hand: his "love is nothing [she] can't fight."

Tears with silver lines... I don't think the girl is wiping her tears with "silver lines," rather, I think the silver lines are a description of the tears coursing down her face. She wipes the tears, yet she still wants it rough. Her shine is simply her brazen personality. Prom girl? or just dressed up prostitute. You decide.

Nevertheless, she recognizes that this guy is pretty sweet, and so he's "got [her] wonderin' why [she] likes it rough." So she tries for a moment to place blame on him with "is it 'cause you don't mean it?" But she knows... she just likes it rough. :)
