1. To become very close to intercourse, but not achieve the desired result.
2. To believe that you are going to get lucky, and wind up with your dick in your hand at the end of the night.
Jimmy thought that he was going to get lucky with Isabelle, but it turned out to only be 'happy half-naked time'... poor guy.
April 19th is the day you send half naked pics to someone you are comfortable with, but not so close to send your nudes.
You could send these pics to your boyfriend, girlfriend, best friend or someone you have a thing with and you can post them on you social media as well BUT YOU CAN’T SEND THEM TO YOU EX.
Person 1: “Happy National Send Half Naked Pics day!”
* send the pics to Person 2*
Person 2:”Awww you mad my day! Happy National Send Half Naked Pics day to you too”
