Holiday post: A night at someone's house

On thursday night, I went to someone's house for dinner. My family, the person's family and my friend Avril and her mom were there. The kids sat in front of the TV while eating dinner while the parents sat at the table like proper people. The person's brother insisted on watching Meet The Robinsons, which is a horrible show, so we had to bear with it. After dinner, we played Taboo (except the mothers). I was in the person, the person's brother, my brother and my aunt's team. The other team consisted of the person's sister, my dad, the person's dad and Avril. In the end, my team won. During the game, the person kept guzzling down nachos and jumping from one chair to the other, screaming, "All hail the freedom of animal milatia!" It gave me a headache.

After that, me, the person, the person's brother and my brother played x-box till midnight. It was fun! We played mortal kombat, fifa 08 and halo 3.

Who is the person?
