Sorry, I think we're talking past each other here. I understand what Bump does/is, but what I (and I believe the original asker) are missing is where the value is. While I can come up with a million use cases for this, e.g. bumping for payments, bumping to share photos, etc, I believe you're in a fairly unique position to be able to express what the core value proposition of the company -- now and moving forward -- is and why it matters to the users. I don't think focusing on the how or what does that.
