Etymology

It is a clipping, at different times, of reputation, repetition, representative and repertory.[2][3][4][5]

Earliest recorded meaning

Reputation: before 1705 in the OED, 1705 in Etymonline,[3][2] where upon rep, “I swear it”, was common 18th-century slang.[3][2] MWU dates this sense to 1677.[6]

Semantic evolution

As short for repetition, a piece learned by heart, it is school slang from 1864, and a single repetition of an exercise in body-building from 1953.[3][2] As short for representative, especially a sales representative, it is from 1896 (MWU has 1789),[3][2][6] and the verb, to act as a representative, from before 1961.[3] As short for repertory, a repertory company or theatre, it is from 1925, first American.[7][3][2] In the 18th century rep also meant a person of loose character (1747), perhaps short for reprobate.[3][5]
