When you shotgun the same bong hit back and forth. So named because the hit feels like shit, and you are (two girls one cup style) vomiting it back and forth. The vomit feels like chunky soup. Thus, you're keeping it soupy.

Widdly scuds?
Me: My girl friend and I were keeping soupy last night, until she blew it all over my face!

You: Wow, how was it?

Me: It was good shit!
