Self-Important Sniff

A quick and audible nasal inhalation made after making a declarative statement about a topic that one's audience supposedly knows little and/or the sniffer considers himself/herself somewhat of an expert. The self-important sniff serves as punctuation to a statement that is typically unquestionable as the sniffer may attempt to pass opinion off as fact. It is typically used by hipsters, although it is also used mockingly, and to some comedic effect, on the Adam Carolla Podcast, as well as The Film Vault (podcast) by hosts Bald Bryan and Dick Anderson.

a person who overestimates their own importance and exhibits arrogant or pompous behavior

That self-important bitch just cut in front of us in line; she's too busy lunchmeating on her cell phone to notice anyone but herself.

Self-Important Program 

Like computer programs that run automatically on your computer, whether you want them to run or not, because their programmers have decided they automatically should. Any person (or program) that takes over from a mind set of self-importance, whether someone has asked them to be the center of attention or not.

Ever since Amy came in here, and took over, things haven't been going well.
Yeah, she's really quite the self-important program isn 't she?

My computer takes a long time to reboot, it has lots of self-important programs running.
