when two people are swinging on swings at the same time and in the same rhythm. it makes no sense because if two people are on a date it's not a double date its just a normal date. smh smh smh makes me angery

Someone that is dating two people at the same time.In between monogamy and serial dater.

to have multiple dates with different people, in a 24 hour span. Unlike "serial dating," it is specific to the two dates in one day - not an ongoing dating relationship with multiple people.
