It started because I hadn't seen him very much in a few days, and was looking to spend some quality time with him. Instead, however, every time I would ask him a question or try to have a conversation, he would have some sort of sarcastic dick statement in reply, his way of being funny. After 3 hours of it, I finally snapped and (frustratedly, admittedly), asked him to be serious and respectful. This turned into a minor bicker, but then we got drunk and it just blew up from there.
