chicken couple
n.— «“Chicken couple” is old Korean slang for a couple who makes people nearby get goose bumps. While it may be sweet to see couples holding hands and saying sweet things, when it progresses to constant text messaging, it is a bit too much. Kissing in public isn’t accepted in Korean society yet, but chicken couples do it.» —“Beware the deadly chicken couple viru” by Jung Hea-won JoonAng Daily (Seoul, S. Korea) Apr. 7, 2005.
