A thought or realisation after ejaculation whereby you have, either, random or relevant thoughts due to your mind now thinking clearly without sexual hormones being active.
After sex:
Girl: Hey baby, what you thinking about?
Guy: I was wondering why Woody and Buzz were named after dildos.

Recollection of sex:
Guy 1: Did you have Post Ejaculation Thoughts?
Guy 2: Yeah, I realised I didn't want to be with her.
