Cover art for Torn Apart lyrics by Stabbing Westward

Oh friggin grow a pair, you whiny sap. This song has nothing to do with the fact that you can't kiss your g/f. If you had half a brain you'd show her the info you found and she'd give up believing her dad. Moron.

But anyway, Drake said it best. You hid something from someone (Not nessecarily your girlfriend, could be a parent or a close friend) and when they found out from someone/where else they were pissed and everything went down the shit hole.
