ADHD and Concentration Camp

Listen up, buttercup! This joke is super dark, like, really dark. You, my friend, are probably scratching your head like a confused squirrel, huh? So, "ADHD" means you have trouble concentrating, right? And "concentration camp" is a horrible place where, historically, Jewish people were sent and suffered terribly. The "joke" twists the word "concentration" from ADHD with "concentration" from "concentration camp." It's a messed-up pun that tries to be funny by making a connection to a horrific event. It's playing on words in a really insensitive way, you dumb-dumb. Got it?
