Conan O'Brien has introduced jeggings to a new demographic (namely, men) who had no idea what they were. Last week he discussed jeggings with guest Tim Gunn of Project Runway. Since the episode aired (followed by Conan actually wearing a pair on the show—watch it after the jump) there's been a full jegging firestorm. Suddenly "jeggings" are popping up in Facebook status updates and Twitter feeds.

Jeggings aren't really anything special—just denim leggings. But the word is catchy, funny, and teetering on absurd. So much that I'm not sure I can take them seriously. For instance, there's such a thing as "shants" (really long shorts) but no designer actually calls them that—it's more of a word used to make fun of them. However, the term "jeggings" has actually earned legitimacy as a type of garment. And Conan wore them like no other, guaranteeing they will live on forever in television history.
