What is the rationale behind "asking for a friend" discussions?

ElectronmanToo much of a good thing is never enough
I'm seeing lots of discussion threads that are posed as "asking for a friend" questions. What is the rationale for that framing? Is there some liability that is being minimized by stating that you are asking for a friend? Is this tactic similar to some of the reviews that write as if they were a dream--- "in my dream I had sex with three strippers, two soccer Moms and a midget at the club" Does either tactic have any benefits to the writer?
Of course, I'm asking this question for a friend.

last commentThe insinuation that is asking for a friend means that person has no friends ;)
The insinuation is that " I don't need to know this, but my friend does ". When in reality, the person writing the story or question is in fact the person that wanting the information in the discussion.
" My friend wants to know what it's like to wear woman's lingerie ".
^ That's what flagooner said about you, lol
It's a cover up in case your wife finds it.
Are you new to this planet? (Asking for a friend...)
It's a joke. See, he's not really asking for a friend wink
It’s a trope that extends far beyond this discussion board. Here are examples across all types of media.

But when I say it I really am referring to a friend.
Most times the friend is about 4 1/2 inches long and lives in his pants.
Well, almost. But only when I'm aroused.
I wonder how many advantage points you get for being hare-lipped, fat, stupid, short and ugly?
