"Dance floor make-out". Usually occurs under the influence of alcohol. Most of the time a DFMO is voluntary, but they can also occur when a drunkard grabs your face and starts making sweet sweet love to it.
That drunk asshole totally stole a DFMO from me at the bar last night!

Acronym for Dance Floor Make Out. Resulting from accidental close contact and banging beats; alternatively, strategically planned as a gateway for 'bigger and better' things. Easily dismissed and not countable as a hookup.
1. We were grinding and I accidentally DFMO'd with a frosh. But it's ok, everyone was too drunk to notice.
2. There was just so much DFMO that I had to get out of there, or make out with BillyBigAss, and that just couldn't happen.
