I dug my key into the side
Of his pretty little souped-up 4 wheel drive
Carved my name into his leather seat
I took a Louisville slugger to both head lights
Slashed a hole in all 4 tires
And maybe next time he'll think before he cheats
I'm still hoping for a sequel to this song, sung from the boyfriend's point of view, in which he tells of her month or two in prison ("Right now, she's probably carving shivs from her jailhouse toothbrush"), warning her that maybe next time she'll think before she destroys another person's property. Or maybe even from her point of view, twenty years later when she's a lonely, bitter cat-lady, wondering why she can't ever seem to hold on to a man. Maybe next time she'll think before she goes berserk after letting her imagination run wild.
As far as we know, based on her own testimony, she destroys her (ex-) boyfriend's truck after merely *imagining* her guy flirting with some gal in some bar. Her behavior might indicate that she's an unreliable witness at best. She don't know that this is happening at all. It makes me want to shout "You go girl… to a psychiatrist!"
But the silver lining of the song is that she might have saved a little trouble for the next guy, who'll now know to steer clear of her craziness.
