1) To become frustrated and flustered at the same time cauz you cant get what you want 2) to be like Neil

I live in the southeast US. I first started hearing "flustrated" by local speakers a few years ago. It was apparent that the speakers were not using this for comic effect; the speakers were quite angry at the time.

I don't think that it's a combination of flustered and frustrated...just a variant pronounciation of "frustrated". If you look at the examples used by the other contributors on this site, I think that they illustrate the use of this term as "frustrated".

To be frustrated and flustered at the same time.

frustrated and flustered, used by Oswego County rubes

{flustered + frustrated}: The state of being pissed off, and doing everything within one's power not to leap across the table and throttle the human source of frustration; when used by a boss describing himself or herself to a subordinate, means "Are you a complete and total moron or just aggressively insolent? We've talked about this seven times."

A mix between flustered and frustrated

the act of not getting any and wanting it cause all you hear is people bitch about it.
