It means pride. It's also a homophone for 'dust'.

What a Japanese person actually thinks
The meaning is fine and positive. The catch is that *hokori* is also 埃 — dust, the stuff under your sofa. Identical pronunciation, different character. Japanese people make this pun constantly.

Meaning

Literally: boast + okurigana
Actually: Pride in the good sense — dignity in what you are or what you've done.
