Flapper

A tourist at a ski resort of subpar skill and intelligence easily identified by their day ski pass arrogantly exhibited and flapping in the wind.

These flappers are ruining the mountain today. I'm getting cutoff by these gomers on my runs down the mountain and on the way to the bathroom.

Yerba mate 

Used to point out when somebody is dancing way too fast for the given music, most likely, though not necessarily, due to the influence of drugs.

Person A, "Radiohead is playing a slow song, but that chick is dancing like it's some DJ Hype DnB."
Person B, "Yerba mate."
