Penis moment

A typically cringy moment you had, usually as a child.
A moment that you didn't realize was cringy at the time but in later years makes you shudder as you think about it.

Example: emo kids posting song lyrics or quotes to social media.

A: ''hey dude, remember that time you fell in love with our teacher and stalked him online and then he blocked you?''
B:''Don't remind me ..''

A: ''penis moment lol''
