a makeout session which is intense enough to be a physical workout. The connotation alludes to a hookup, but the word can also used in the context of a relationship.
Dude I got some awesome cardio in yesterday!

It was a date at the movies; of course there was some cardio!

So Nicole, did you get any cardio in on after school on Friday?
