"It is told that someone once asked Rav Elyashiv how can there be Talmid Chochom who is a Baal Gaava? Rav Elyashiv answered him that in fact there is no such thing. 'Either you don't know what a Talmid Chochom is or you don't know what a Baal Gaava is.'" (source)

"The mark of someone who is a ba’al ga’ava, a haughty person, is that he walks with a straight spine, upright, in a way which shows that he feels greater than everyone else. A humble person, however, tends to walk more bent over, in a submissive manner, realizing his lowliness in comparison to his Creator." (source)

"From a superficial understanding, he is a baal gaavah, but it is more than that. A person can be a baal gaavah because he thinks he is to be praised in a certain quality. But when it comes to other areas, he knows that he is weak in those areas, even though he won’t admit it. He only boasts about what he’s good at." (source)

"The ba'al ga'avah feels independent and autonomous , and hence boastful and proud. An anav, by contrast, while appreciating the religious mandate for human effort and initiative, understands that Hashem has endowed him with whatever abilities he possesses, sustains him, provides him with opportunities and crowns his efforts with success." (source)

"You, whom this Torah genius could have walked circles around had his mind been younger and keener, you, who had the audacity to smile when you approached to help him. You're such a ba'al ga'avah."" (source)

"He didn't 'forget' to mention you in the credits, he's just a plain baal gaave!" (Glinert)

"He's such a baal gaiva--every conversation he engages in, he steers toward talking about how great he is!"
