(noun) A Police Officer (Brit., vulg.)

Derived from the well-known British spoonerism, "I haven't had a cunt all night, drinkstable!" (an inebriated corruption of "I haven't had a drink all night, constable!" - commonly offered in one's own defence when apprehended by the forces of law and order for some minor motoring infraction - eg., running down a Sunday school outing or driving one's Bentley through the Food Hall at Harrods).

Adj. Something that is expected to have a long lifespan by virtue of having existed for a long time, based on the lindy effect, named for the New York restaurant Lindy's, coined by Albert Goldman and popularized by Nassim Taleb.
