Should This Go To Urban Dictionary, Too?

I was driving around the other day and saw two crusty-punk girls on bikes stopped at a streetlight. Apparently they wanted to make the best of their time there, so they filled the wait by making out.

Before we proceed, let me say that we're cool with a little girl-on-girl, and we're pretty thrilled to see a cyclist stop for a red light. Now that that's out of the way...

How do you guys feel about a subset of muffdiving that only applies to crusty-punks? We can call it dumpster diving.
