fare evasion (on trains)
Slang for riding a train while only paying for the first and last portions of the journey, skipping the fare for the middle section. Named because a kiseru pipe has metal at both ends and bamboo in the middle — like a ticket that only covers the endpoints.
煙管乗車は犯罪だ。

The word comes from Cambodian (khsier). The kanji 煙管 is an ateji reading. For the fare evasion sense, the metaphor is: a kiseru has metal (金) at both ends with bamboo (竹) in the middle — like paying (金 also means 'money') only for the start and end stations. Common collocations: 煙管乗車 (fare evasion by train), 煙管をする (to evade the fare).
