Similar to a detention in the fact that you are kept behind after finishing time,its a way for large multi national companies to hold employee's behind for working too quickly/hard and finishing early , usually involves some kind of team building excercise or pointless tidying up and painting .
Employee 1 " awesome were doing really well today i'll easily make it home in time to watch the game tonight"
Employee 2 " I doubt it! the boss has just given us an After work detention "
the illusion, manifesting a few days after becoming engaged, that women you know other than your fiancée have become vastly more attractive than they were before your engagement, causing you to temporarily question your decision to propose.
Origin: The engagement is sealed with a diamond ring, and your female friends aren't actually any more attractive than they used to be; hence, the "diamond deception."
Guy 1: Hey, congratulations on your engagement last week!
Guy 2: Thanks, bro.
Guy 1: How does it feel?
Guy 2: Well, honestly, these last few days I've been noticing how hot all my female friends are. But now that I'm engaged to be married, I'll never be with any other naked woman again!
Guy 1: Oh man... you're totally suffering from the diamond deception!
When you do something bad that doesn't warrant a detention. Instead, you have to face the wall of the cafeteria and starve while everyone else is eating. In my opinion, it's only going to make you want to get into more trouble.
When you deceive your parents that you doing homework by shifting tabs. You put google on one tab and you put the actual website you looking at on another.
