DBFS is an internet abbreviation for "don't be fucking stupid." Its primary use is to admonish someone for a stupid question or their lame behavior.

DBFS is often preceded by a hashtag (regardless of medium): #dbfs

Close to the Super Bowl in late January/early February is the time of year when the Delusional Browns Fan Syndrome starts....an annually occuring disease characterized by intense euphoric hope completely unfounded in reality, logic, or past experience. It gets worse until the NFL Draft in the spring, usually plateaus over the summer months, then hits its peak in August when "Undefeated Preseason Championships" are won. This is usually when talks of "Division Titles" and "Playoffs" become numerous. The symptoms then typically go away after another month, when logic and reality have returned after actually seeing the team perform against top level NFL talent. Then, typically depression sets in beginning in October when any chance at a respectable season, let alone playoffs, is completely gone. There can be residual symptoms during the NFL playoffs if a new regime is hired, in which case the disease process is typically more intense the following year. Sadly, there is no cure or known treatment for this largely inhereted and regional illness. Side effects include: drinking heavily, swearing, crying, family feuds, the Monday Blues, obsession with college quarterbacks, general attitude of cynicism and hatred for all things black and yellow.
Steve: I really think Hue Jackson can get the Browns to 6-10 next year after they sign Kirk Cousins, a free safety, 5 wide recievers, draft Barkley and Chubb, and Jimmy Haslam has to sell the team because of the FBI investigation into his racist Pilot/Flying J underlings

Brad: Dude, your DBFS Delusional Browns Fan Syndrome is the worst I have seen since 1999 when you got that Tim Couch tattoo....

DBFS is a cheap ripp-off of DIAF and is a quick way of suggesting that a person die by firing squad.

It can also stand for decibels relative to full scale but who gives a shit?
Person 1: Hey buddy! Guess what!? I just got lucky and got tickets to the Heart/Journey concert this week. They just sold out.

Person 2: dbfs?

Stealthie 

when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.

This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"

FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"

The grindset is a contemporary ideology of self-exploitation disguised as strength, deeply tied to the aesthetics of the “sigma male” and to new digital forms of patriarchy. It promotes the idea that human worth depends on productivity, economic success, absolute emotional control, and the ability to work endlessly, turning vulnerability, rest, community, and tenderness into signs of weakness. Beneath its rhetoric of discipline and power often lies a profound inability to relate healthily to pain, fragility, and human interdependence.
“That’s the grindset, brother. While weak men sleep and complain, sigma males stay disciplined, work in silence, suppress emotions, and build power while everyone else wastes time chasing comfort.”
