Yep. The people who fling it around clearly don't have a specific definition for it. Most often, their definition appears to be "anything to the Left of me".The primary use of the word "socialism" has been to use it as a fear word.
But, as with myriad other examples, we've devolved into blurting intellectually lazy, simplistic hyperbole at every opportunity.

Socialism is central economic planning. It's not a 5,000 piece jigsaw puzzle, guys. Sure, there are a lot of variations of it. Full socialist ownership of industry, fascism (token private ownership but companies must follow government economic plan and get major decisions approved), crony capitalism (companies pay off politicians to pick market winners). But in the end, either government controls the economy (socialism) or we make our own choices (capitalism).
It's not that hard
