Untergrundtango

Untergrundtango is another german word for Pogo (a dance style on punk rock shows).

- Look, the crowd is doing Untergrundtango in front of the stage.
- The Untergrundgrundtango at the last show of NOFX was awesome!
- I am too old for Untergrundtango. I prefer to drink a beer at the bar.
