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.
