Will you get an answer? Chances are, you will. The male friend is exhibiting behavior known as Male Answer Syndrome. It's the compulsion by many individuals (mostly men, but sometimes women) to answer questions readily, regardless of knowledge.

Reader Alex Moss concurs:
I first heard the phrase "Male Answer Syndrome" in "Eyebeam," a comic strip at UT (University of Texas at Austin) in the mid-1980s. I couldn't give you an exact date for this particular coinage, but if memory serves me, the phrase was introduced by Eyebeam's girlfriend Sally — she accused him of suffering from "MAS," he asked what that is, and the rest is history. I would actually post it on your site under "MAS." Your post is dated 1998, though the citation from the Seattle Times itself doesn't have a date on it, perhaps it's older. Anyway, the author of the comic is Sam Hurt, I don't know him but here's his home page:
