The habit of committing rancid, horrible, disgusting, and such awful acts, that you will be sent so far down into hell and even Satan himself with have to dig deeper just to get to you.
Also just doing stupid things for fun when you're bored, like setting a shopping cart on fire.
Man 1 - "What do you want to do?"
Man 2 - "We could go commit some Dumbfuckery, for fun,"
Man 1 - "I don't see why not,"

What Mark Zuckerberg thought of users who forfeited their personal data to his site, Facebook, in his college days.
He still believes everyone who uses his sites (Meta owned sites) is a bunch of "dumbfucks".
Mark Zuckerberg use Signal, dumbfucks use WhatsApp. You can stop being a dumbfuck and use the privacy oriented services who can only collect your data by the most and don't sell it to 3rd party vendors.
People who think someone is interested just because you're nice to them, when in truth the only reason you talk to them is to fulfill your "one good deed" for the day! -_-
