Getting harder and harder to keep up

Here's what I learned today: the meaning of breadcrumbing

I asked a friend if he knew what it meant and he thought for a few seconds and then quietly answered: Not getting lost in the woods?

So I received a spam email about how to deal with breadcrumbing... (a vacuum cleaner?) but here's what it is:

If you’re active in social media circles and in the online dating game, you’ve probably ran into issues with breadcrumbing—the act of sending flirtatious, but non-committal messages (breadcrumbs) that end with you never meeting the person in real life. This new social media and online dating trend is both annoying and frustrating for the person being breadcrumbed. Think of it as the new ghosting.

I had heard of ghosting because I watch MTV's "Catfish" --ghosting is when the person simply disappears with no explanation.
