flak, from the german “fliegerabwehrkanone”, originally referring to land-based anti-aircraft defense systems, has more recently been used when speaking about low velocity shrapnel-based war-time technology (ie the ‘flak jacket’ etc).

figuratively, this phrasing is used to allude to broadly targeted aggressive interpersonal behavior.
‘he was feeling insecure and start shooting off a bunch flak without realizing she was the one getting hit by most it, what a careless b-st-rd’
anti-air firepower, often seen as black smoke that erupts unexpectedly in midair, although at a certain range (there is a limit as to how far a flak sh-ll can go before exploding in midair, thus allowing a pilot of an aircraft to antic-p-te flak).
“if you were paradropping, a flak sh-ll will pretty much kill you. if you’re lucky, you’ll be blinded by the black smoke of the flak. paradropping is scary in this case, but someone’s gotta grow some cojones and do it.”
