Why does this man irritate you so? Well, it might have something to do with the fact that he's a lying douchebag whose douchebaggery seemingly knows no limits and that he's so fucking smarmy in his non-knowledge that anyone with half a brain wants to spew a 10-mile-long trail of vomit at the sound of his whiny, condescending voice.
And did I mention he's a douchebag?
I like your style.
