scalf,


First, I'm hardly an expert. But, I just happened to finish reading a book that covered this subject. The plural of Suburban Poker Man would be "Suburban Poker Men" because the phrase has something to do with "men." But the plural of "walkman" would be "walkmans" because, according to Steven Pinker, "in no sense does a walkman have a man." The same extends to words like "lowlife," for which the plural is "lowlifes."


Also, the same applies to verbs like "fly out" in baseball. The past tense is "flied out" not "flew out."


Hopes this helps.
