undercut hairstyle
jocular, humorous
Jocular term for an undercut hairstyle, popularized after the 1923 Great Kantō Earthquake. The name plays on the idea of a 'disaster cut' because the style was seen as a drastic change. Compare with ツーブロック (two-block), a more common modern term for a similar style.
