Do y’all have a particular movement that indicates that you’ve gone from ‘kind of involved’ to ‘ready to Fucking Go’?

Let me give you an example.  I was talking to a buddy of mine about television and the decline thereof, and I was kind of casually involved in the conversation with my feet kicked up on another chair and my chair tilted back onto the rear legs, and then he mentioned Supernatural and there was this loud thud as my chair went back onto all fours and I pulled my legs in and sat up straight.  My roommate’s immediate response was “moRAN NO YOU HAVE CLASS.”  Naturally I ignored her completely and went “okay, you wanna talk about Supernatural, we’re going to need some time, do you have an hour to listen to me bitch.”

Another example would be the time I kind of greyed out and ripped someone to shreds verbally and later my roommate said that she knew it was going to happen because I straightened up and folded my hands on the deck of my computer.
