This post makes me laugh my ass off. Getting pissed off about saying "brashly assumed"

Meaning:
Brash or brashly: intrusive or presumptuous, as persons or their actions; insolently rude; uncivil:

So basically jfesler said he was being a @#$! to assume the guy could afford a piece of PDI glass. And tells him info about said glass.

Then DB62 gets pissed and thinks the guy was being a @#$! to assume he could afford a piece of PDI glass. And doesn't care what he had to say about it.

Oh PINSIDE, you so crazy!

Topics like this, are the answer to this Question.

YES. I think you took it out of context.
He was stating it is rude "brash" of him to assume solely that by your collection you could afford it.

So in his defence, he used the word correctly.
And you are getting upset for misunderstanding the context on which it was used.

Given your collection I would think the same thing. However that would be "brash; presumotious, rude and uncivil" of me to assume that, not knowing anything else about you.

Which he stated.
