I get this a lot at work, and the questions the colleagues ask are never a "quick answer". The answer always requires more context than the asker realizes. Sometimes it turns out the context that is really driving their question is not even close to what they thought they were asking, so the real answer goes in a complete different direction.
I try to be subtly snarky in my reply "there is no such thing as a 'quick question'" but have given up getting these people to realize their intellectual laziness. I suspect the main reason is they really think there is a Yes/No answer, or maybe they think I'll move their answer to the top of my stack because it will be a quick one for me.
Even here, I see posters asking "I have a quick question" and then there are multiple pages trying to get the full context out of the asker to properly respond with all the complexity in the answer.
Just ask the question.

After reading your comment I need to take a nap! Good points 
They're saying it in order to get your attention. If someone says it's a quick question, people are more apt to pause what they're doing to hear what it is versus saying they're busy or waving someone off. I don't think it has anything to do with intellectual laziness for most. More like they just played you psychologically. They may not even realize they're doing it, they just know subconsciously that they'll get a better response when starting the question that way. Similar to how people asking for a favor always apologize before asking the favor. Studies have shown that apologizing beforehand reduces tension and makes the other person more receptive to the favor, even if there's nothing to apologize for. It's also the same reason apologizing is the first thing to do when de-escalating a situation.

Every workplace has that guy who thinks he's (it's usually a dudebro) better at something than anyone else on the planet, so I'll usually go to them in a meeting with a quick question involving complexities they've never encountered then watch them grind to a halt in front of their more knowledgeable peers.
Thanks to Dunning-Kruger it's rarely effective, but it's still a pleasure to watch.
I see the situation you describe, and yes, as a trip-up method that might be entertaining. 
My colleagues are asking me through Skype texts, one-on-one, so they are really looking for the answer. I am the DudeBro because I have been heavily involved in the projects creating these processes, so I know the answers. But I also know the apparent misdirections that lead to me determining what the person really should be asking, and direct our solution where it will be productive, not necessarily the first "quick question".

Yes, I think they use it as a shorthand to get to the top of the stack. The thing is, I will help them regardless, so it's somewhat annoying that they don't trust me to work as a team member to help them.

If it really is a short question or requires only a minimal response, then "quick question" away.
I also would not mind if the question was really simple. The thing is, by the time they get to me, they could not arrive at a solution by asking others because their question really is complicated
Cuz who wants to ask a slow question

That's not too far off. Many times I get the impression they want a quick, complete answer to take it back to the higher executive to look good.
Which is why I often end up slowing them down, as the path they are on may not be where they should be going. Or it really is not that simple of an answer.
