It marks you as wanting to belong to a certain tribe for sure, even if the definition of that tribe has been excised from the originator of the term: people use it because they see people that they admire or want to be like using it. In trump's case the tribe is about trump, in Heinlein's case the tribe isn't about Heinlein.

Like people walk around with their pants around their knees because they see that thugs wear them like that and they dream about being thugs. Or people who call each other "bro".

These are also normally people who weight the style more than the substance.

I found Heinlein's works to be the full gamut of interesting and disgusting. That one word was amusing enough for me to use, and somehow that paints my entire character? It was one of the more innocuous things that could be lifted from his writing. You're trying to extrapolate far too much from that.
