RIP

• R.I.P.

Learned borrowing from Latin RIP (requiescat in pace) and an initialism of rest in peace.

• (standard)
  • IPA^(key): /ɑː(ɹ) aɪ ˈpiː/
  • Rhymes: -iː
• (Internet slang, humorous, ironic)
  • IPA^(key): /ɹɪp/
  • Homophone: rip

RIP

1. Initialism of requiescat in pace, requiescant in pace, and rest in peace.
   • 2019 May 12, Alex McLevy, “Westeros faces a disastrous final battle on the penultimate Game of Thrones (newbies)”, in The A.V. Club‎:

     But Sandor shoves his knife through his brother’s head, and when that doesn’t stop him, he sacrifices himself to kill his sibling, knocking them from the tower and plunging into the blazing fire below. R.I.P., Sandor Clegane and your malevolent brother.

2. (derogatory) Initialism of rest in piss.
3. (rare) Initialism of rest in power.

• The phrase is never used unironically in reference to actual sleep or rest for the living; it refers only to the dead.
• Typically found as an epitaph on a tombstone or in an obituary (and hence on graves in Halloween decorations, cartoons, etc.).
• The phrase is sometimes used as an epithet when referring to a deceased person, as in “This university was founded by Thomas Jefferson, RIP.”
• Also used as an indirect way of stating that someone or something is (literally or figuratively) dead.

• RIP in peace

RIP

1. Routing information protocol, a dynamic routing protocol used in local and wide area networks.

Originally coined in Selker et al. (1987) as an acronym for rearrangement induced premeiotically, which was later renamed repeat-induced point mutation in Cambareri et al. (1989).

• IPA^(key): /ɹɪp/
• Rhymes: -ɪp

RIP (uncountable)

1. (molecular biology) Repeat-induced point mutation, a process by which both copies of duplicated sequences are mutated.
   • 1987 December 4, Eric U. Selker, Edward B. Cambareri, Bryan C. Jensen, Kenneth R. Haack, “Rearrangement of duplicated DNA in specialized cells of Neurospora”, in Cell, volume 51, number 5, page 750:

     The RIP process can be extremely efficient. A linked duplication of 6 kb of Neurospora DNA, whose elements were separated by 7.5 kb of bacterial and unique Neurospora sequences, never survived a cross unrearranged.

   • 1989 June 30, Edward B. Cambareri, Bryan C. Jensen, Eric Schabtach, Eric U. Selker, “Repeat-Induced G-C to A-T Mutations in Neurospora”, in Science, volume 244, number 4912, page 1573:

     Thus, the RIP process results in point mutations, consistent with the results from the heteroduplex analyses. On the basis of this information, we suggest changing the name of the phenomenon from "rearrangement induced premeiotically" to "repeat-induced point mutation."

   • 2003 April 24, James E. Galagan et al., “The genome sequence of the filamentous fungus Neurospora crassa”, in Nature‎, volume 422, page 860:

     To investigate the impact of RIP on protein families in Neurospora, genes were clustered into ‘multigene families’ on the basis of an all versus all comparison of protein sequences (see Methods).

RIP (plural RIPs)

1. (US, law enforcement) Initialism of reduction in pay.
   • 1972, New York Magazine, volume 5, number 5, page 32:

     […] recommended as punishment a 55-day RIP (reduction in pay) but was overruled by higher authorities […]

   • 1991, Vincent Murano, William Hoffer, Cop Hunter, page 73:

     He admitted to his indiscretion and accepted a five-day RIP (reduction in pay). What the hell is going on? I wondered. We let a captain with possible O.C. connections off the hook, but we bust a patrolman for having a drink!

RIP (plural RIPs)

1. (biology) Initialism of ribosome-inactivating protein.
