Loosing your connection to the internet
Johnny was interneutered suddenly by his cable company which left him feeling much like his cat who was neutered a few days ago. |Urban Dictionary|
The voting is currently pretty negative on interneuter (the urban dictionary is an interactive dictionary 2.0 of course). But I like it. I think it's even fun to say.
It is (far too often) a handy term when using a web-enabled phone or PDA to answer a question and you lose connection. I'm sure this has happened to most information professionals at one point or another.
