I'm sorry I'm late, but I was caught slow-dancing with some loser in the hallway.
Nothing is more annoying than having to slow-dance with some random guy when you're in a hurry.
A close-contact dance between a male and female that most often leads to something more.

Sam: Yeah, they were practically joined to the hip all night! I saw them sneaking outside together afterwards.
