(chiefly a stronger form) Jesus Christ.
Origin of jesus-h-christ
- Extension of Jesus Christ with a fantastical middle initial, perhaps derived from a reading of ΙΗΣ (IĒS), a Greek-alphabet abbreviation for Jesus (ΙΗΣΟΥΣ) as three initials in Latin letters. See "Christogram" at Wikipedia.
- The expression dates to at least the late 19th century (although according to Mark Twain, it was already old in 1850) (Smith 1994, p. 332).
