Postcoditis 

Social snobbery based on where you live, where you work, or where you grew up.

The lady was not invited to the party because the hosts were suffering from postcoditis.

Postcoditis by Urbankatie July 27, 2025

postcoitictal 

The extreme fatigue state following sexercise. A combination of postcoital and postictal (the confused, sleepy state following a seizure).

I was so postcoitictal after my date last night. A bomb could've exploded next to me and I wouldn't have known.
