Main-stream media 

The Main Stream American Media (MSAM) is the most prolific source of blatant poltical bias in the whole world. Every word of every sentence pronounced by the journalists in the mainstream media is entwined with vile lies and conspicuous BS. This is applicable to both sides, but its mostly the left.

"Its probably another Main-stream media coup." or " As trustworthy as the mainstream media depicting Trump" ( sarcasm)

Mainstream Media

The most widely consumed media networks and publications in the West. Often they're either neoliberal or conservative and their views follow moneyed interests. The mainstream media is where most low-information voters get their politics from.

Definitely not abbreviated "MSM" (more commonly understood as "Men who have sex with men")

The Mainstream Media is so out-of-touch with the working class!

M.S.M.H. (Mainstream Media Hysterics) 

Mainstream Media Hysterics is the absolute belief and blind trust people have in Mainstream Media coverage and reporting.

Daniel has a problem in that whatever is so obviously staring him in the face but the mainstream media says otherwise he'd rather trust lies perpetuated by the MSM than his own experience. He's most definitely suffering from M.S.M.H. (Mainstream Media Hysterics). It's really quite sad.

Mainstream Media

A term used by people who get all of their "news" and "information" from youtube, to describe any source offering facts that don't comport with the nonsense they've been consuming. More hardcore idiots will use the acronym MSM because they reference the mainstream media so much.

I went to buy some light bulbs and the cashier started telling me about how the mainstream media is covering up UFOs. When I told him I didn't have time to talk, he told me I had been "blue pilled."
