As an old, learning the new slang is a wonderful chance to learn words of power that will make everyone around you flinch under their force.
Utter a "that's bussin for real," and watch those around you fall to their knees, and add a "poggers" to hear them wail and grind their teeth. Sprinkle a "skibidi" in to really drive things home.
The kids change the slang all the time. Did you know that dope apparently no longer means cannabis? Apparently the kids think it means exclusively heroin (horse).
I don't know, we called it dope in when I was in high school (you were probably a very young child). You were in your 20s at the millenium and that wasn't that long ago. Perhaps you were the kids that changed it?
