blowhard 

As mentioned in another definition, a very braggy and pretentious person, overly prideful and arrogant. See egotist.

Also could be an insult to anyone; the definition of this other insult is totally unrelated to boasting or bragging. We all know what blow means.

You blowhard!

You blow hard!
