Little friend; use of the prefix "mini" to produce an affectionate diminutive from the Russian word "drug" (transliteration) or "drook" (phonetic transcription), corresponding to the French "Petit Ami" which extends to the definition "boyfriend" and even to the feminine form "girlfriend." Generally meaning "compatriot" or "close associate." Related to the already-cited "Slooshie" derived from Russian "slushitj" from "slykhitj" meaning to hear or listen (depending on aspect: perf/imperf). Extract of dialect evolved from book/movie "A Clockwork Orange."
