Someone who generally starts their day in the afternoon, getting out of bed after 12pm.

It could be from late nights or just general laziness
Mike: It's 1.00, how are you not ready yet? You've had all morning.

Sarah: Well actually I went to a party last night so I only got up like half an hour ago.

Mike: Geez, whatever. You're such an afternooner.

The act of having sex during the afternoon hours of the day as opposed to the far more common nighttime hours.

The term was originally coined in the 1976 hit song "Afternoon Delight" by the Starlight Vocal Band. Due its lighthearted musical style, the song is often misinterpreted as being one about the general fun and innocence of being in love. Only upon close inspection of the lyrics does it become obvious that the song is actually about having sex during the afternoon hours of the day.
I went home to have lunch with my wife, but we ended up having a little afternoon delight instead.
