inert by speckd December 11, 2007
The state of being so engrossed in one's device (iPhone, iPad or equivalent) that one remains oblivious to all surrounding activity and communication and to the social norms that once governed them. Accordingly, the Law of iNertia states that a person engaged with his or her device will remain so engaged, regardless of any forces acting upon them to achieve a change of state. (The Law of iNertia thus operates contrary to the Law of Inertia, according to which a body at rest will remain at rest and a body in motion will continue moving with a constant velocity unless acted upon by an external non zero force.)
"Hon, did you ask Mike to take out the trash?"

"Yeah, but he was iNert. I'll try after dinner."

I've heard that inert gas asphyxiation is the least painful way to die, so my idiot sleep-deprived self wrote an Urban Dictionary definition to help people who were searching for it. I am fully aware that this idea is pointless.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
