Usage of the word within the in-group may mean one thing but from the out-group it means a whole different thing.
You're basically calling yourself a slave and justifying it with blissful ignorance.
You're saying 'words mean what I say they mean and I'm ignoring all shades of meaning but the ones I choose'.
and you can't see that in a professional culture if some people are "suits" and some people are "geeks" it's a drastic disadvantage situation in favour of stereotypes over reality.
And plus bro I wouldn't call you bro at the office but you'd surely call me a geek.
