You know, English is a malleable and transitional language. I'm an elder and I've witnessed society change the words it uses to describe people, places and things if they've changed a bit or even if they haven't changed. I give you some examples, would you like to suggest some of your own?
negro= black = Afro-American= AfricanAmerican
stewardess= flight attendant
nurse= male nurse
mortician= funeral director
mulatto=people of color
indian= native American
whore= sex worker
That's not an example of a change in word usage. Those are words that have gone in and out of fashion for political and other reasons.
Changes in the meanings of words are more complicated and include momentarily, which at on time meant 'for a moment', but now can mean 'in a moment'.
Apparently this came about from flight attendants announcing to passengers on stopover flight that they would be landing in a city momentarily - meaning they would be departing again shortly thereafter.
Another change is hopefully which went from meaning 'with hope' to 'with a bit of luck'. At one time "she answered the phone hopefully" described how she was feeling when she answered the phone, but now is more likely to mean that the speaker hopes that she did in fact answer the phone.
Umpy, get some sleep, hon.

And yet, OP, a troll is still a troll.

Rap and hip-hop are not exactly the same thing.
Hip-hop is a culture and lifestyle and rap is the music of that culture.
B-boying and graffiti are other examples of hip-hop culture.
