From Habr:
Once, 10 years ago, I was surprised how suddenly the radio amateur code "88" (something like polite playing with radio amateur girls, in different manuals treated as "love and kiss", "air kiss" and so on) became popular.It was a good tone to insert this code during radio communication with YL (from “Young Lady”). So, suddenly began to meet this code painted in the entrances, on the walls of houses, etc. Insightful photographers probably guessed that, as a rule, this code was accompanied by a small number "14" for radio amateurs. When I was finally deciphered this message, I was somehow very upset. As if something bright and pleasant dirt was blotted out.
