Over-protective bestie?

Lately, these good-for-nothing "wannabes" are really starting to get on my nerves. Especially this one guy who thinks he can break her heart and get away with it. No sir, you can't. Not till she has me by her side. You think it doesn't matter, really? Make her cry, break her heart, let her down.. because you care about her, right? I'll show you who cares about her, Mister-I'm-not-man-enough-to-even-answer. The truth is, to not want HER, you must be gay. Of course, how could we miss that?!  I'm sorry lover boy, you lost her. Try not to break into tears just yet, save it for when I come kick your ass.
