We know D.C. Get our free newsletter to stay in the know.

Remember the last time you returned an online purchase because the item looked entirely different upon delivery? According to the editors of DailyCandy.com, there’s a term for that situation: “mouse trap.” Launched in 2000, DailyCandy quickly rose to sassy e-newsletter stardom with a plethora of goof-proof makeup tips, event listings, and guides to the hottest shopping spots in select cities. Since then, it has spread from Los Angeles to here, and now it looks to bring its juicy jargon to everyday chatter. The site’s editors’ second book, The DailyCandy Lexicon: Words That Don’t Exist but Should, suggests terms like “textual frustration” (a string of flirtatious text messages that fail to produce results) and “GPX” (a tracking system to monitor your ex’s moves). DAILYCANDY D.C. EDITOR ERIN Hartigan discusses THE BOOK at 7 p.m. at Olsson’s Books & Records, 1307 19th St. NW. Free. (202) 785-1133.
