It's hard to talk with all that cock in your mouth.
I remember once in high school, a friend and I were walking to class when some troglodyte jock (you know the type) yelled out "fags!" as we passed him. Naturally, he waited until we passed, since these types of assholes typically don't have the balls to say that sort of thing to anyone's face. Immediately after his pathetic attempt at an insult, I spun around to face him and said quite loudly "What was that? I couldn't hear you with all that dick in your mouth" and then continued walking. He never really spoke to me after that.
Your comment reminded me of this somewhat hilarious situation.
