From an eminem song, from ~the year 2000. That's the only place I'd heard it before

I think it was from urban slang in the 90s.

I think it comes from british slang where to blast someone means to exclaim annoyance at them. May have heard the exclamation like "oh blast it" when something goes wrong.

Thanks. I’ve never heard this in the states.

I've only ever heard it in the episode "I will put your kids on blast" of the podcast Harmontown:

Don't watch Family Guy then? "Blast!" is one of Stewie's favorite expletives.

A bit obscure for the US, but fits well as a pun when the topic is NASA and JPL.

Common American (and online) slang meaning calling out someone. I believe it originates from Chicago or the Midwest but it got popularized on social media like a lot of other slang in the 2010s and now is pretty much used everywhere especially among Gen Z.

As a Gen Z, TIL "put on blast" is not just a normal common phrase

An informal definition of "blast" is a severe verbal reprimand, and it is unlikely you've never heard it used that way because it originates in the US in the late 19th century. "Put on blast" means to embarrass publicly by admonishing, and also originates in the US, but is much more recent. Compare to "put on full blast," (sound familiar?) which has a different but related meaning, but like all these uses originate from Old English blæst "a blowing, a breeze, puff of wind," and later, blast furnace, the idea of forcing air to increase combustion for smelting iron.

It's a newer aphorism popular amongst the wannabe trendy younger folks for the last couple of years. Fairly sure it's going to fade from normal vernacular eventually.

Yeah, not that new and has wide popularity.

Common phrase in the military going back at least 15 years. Suppose “putting on blast” is more common in that context?

Other than the tone of vile disdain, it's not unheard of for phrases to disappear from everyday usage.

Another sign of getting old is it's not just the whippersnappers using slang I don't understand, now it's showing up it news headlines too.

Also, current slang in headlines seems like an odd choice anyway. I get there's a not-great pun there and all, but the article doesn't seem like it's written for an audience that already knows what "on blast" means.

You're > 22 years out of date on that one then, a google search showed 'on blast' being used since at least the year 2000
