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

When you're at a party, and that ugly guy won't stop hitting on you, the DBF would say, "dude, she's not into you, walk away." If that doesn't work, you slap that ho.

"Amanda, you're our DBF"
