I never have but it seems to be a well-used romantic set up on TV and in films. That Marianne in Sense and Sensibility went for the double whammy, she twisted her ankle and got caught in the rain before that bounder Willoughby rushed along to save her. If I twisted my ankle I'd be too busying yelling 'Ow, ow, my fucking ankle. The bastarding thing has twisted. Ow, ow'.
Maybe I'd be too self-involved to recognise it as a prime snogging opportunity.
