I don't particularly care if a normal word, which is in plenty of dictionaries, is co-opted by a small group of people. My friends won't know this secret meaning, my family won't know that, whatever is on the TV, Radio, or Cinema won't know that.
And now this conversation is completely off topic.
The internet is so hyper partisan that even normal, boring usage of the English language is now weaponised as shibboleths.

That's without even looking for a thesaurus. Not that I'm supporting this alt-definition of noticing, but your question seemed pretty trivial to answer.
Maybe it's better to assume that most people in the world aren't evil degenerates unless there's hard evidence to the contrary.
