RU14692

A sentence meaning:

Are you one for sixty-nine, too?

Written on toilet walls in solicitation of a mutual blowjob, usually followed by telephone numbers. The two partners lie against each other with their heads in the other's crotch and perform fellatio.

Chuck had written RU14692 under the glory hole in every stall in most of the tea rooms along the South beach.
