I eat pudding with the back side of a spoon..
I make fart noises with my hands when I'm nervous or bored.
When I talk to people I'm not comfortable with or if I'm nervous, I make a click noise with my mouth like, every 5 seconds.
I say "like" far too often. (I live in the valley of my city, so that makes it kind of funny...)
I always set my silverware upside down on the edge of my plate when I'm not using whatever utensil.
Oh. And quoting movies ALL THE TIME.
Talking in accents to my cats and family.
Making faces when I sing.
