It's worth noting that, based on the paper, this is really "words known better by males (who complete free online quizzes) than by females (who complete free online quizzes)". This likely explains a significant amount of the fashion and video game words. For example, it seems unlikely to me that 60% of all US and UK women know the word "peplum", but reasonably plausible that US and UK women who complete free quizzes on the internet also spend more time browsing clothes on the internet than the average woman, and would therefore have more knowledge than the average woman about clothing terminology.
