Post Nut Clarity
Post Nut Clarity is like having a steak dinner in front of you, but you just ate. It should be great and it normally is, but you have already had enough. Post means after, as in after you leak juices from your penis, and the clarity is from the thought beams that shine down into your head.
Person 1: Yo bro Samantha gave me head but I got post nut clarity after so I did the dash

Person 2: damn that sucks bro
