Hmmmm, back to MSBJ's question. Honestly, I don't know. What is the location, is the guy intersting (aside from his Speedo), how much have I had to drink... All factors that would have an influence on my actions!
There it is! It is all about the drinking. So what you are saying is that after a few drinks the Speedo becomes more interesting. SO if one wears his Speedo around a bunch of drunk chics, the odds are in his favor. I may have to try that.
