Picnic date with a Bluetooth speaker for some background music, perhaps? I often see that in parks/beaches/etc, and as long as volume is reasonable I don’t think anyone minds.

I found this confusing as well. She probably meant to "Forget" the device when the Bluetooth pairing with the headphones is lost.

I followed the link through to the video interview; it's not a lot clearer, except that she's definitely talking about trying to play a song (and it not working, ruining/frustrating the moment). Follows with the example 'or you're in a car, you have to pull the car over. To play a song?! On a date!'

I've just been putting wired headphones on my date's ears. It makes it harder for her to run away too.

The idea is that you're at home with the other person and want to listen to some music from a bluetooth speaker.
