While I understand what you mean, I prefer not to play with word definitions. For me, spoken language is a democratic process, and words mean what the majority of people believe them to mean. That's how language develops. It's called semantic shift. If the majority of people have the "wrong" definition, then it perhaps the word has simply shifted its meaning, and it's time to acknowledge that.
That said, what is the colloquial meaning of socialism? How does the common man on the street define it? I'm from Eastern Europe, and here for example, anyone you ask will tell you that socialism mean the way things were in the Warsaw Pact - a one-party state, propaganda, jobs provided by the state, and all life organized by the state. Nobody here would call Norway socialist. In fact, most people here would simply call them a capitalist country, because to us, any country West of the Warsaw Pact, including Norway, was simply a capitalist country. Socialism meant Us, and capitalism meant Them, and Norway wasn't part of Us.
Of course, that's what socialism means in Eastern Europe, perhaps it has a slightly different meaning in America.
Oh, that's easy. In rightwing America today, socialism means "Anything I don't like". So that they all think Putin is acting like a socialist. Or that Al Qeda are socialists.
