I have no guesses on "пихливий," but I would assume that the second two words are "невоспитанный москаль" -- meaning "a damned Rooskie who wasn't brought up properly."
ЗЫ: In general, "москаль" is to "русский" as "stupid Limey" is to "person from Britain" (in the US) and "stupid Yank" is to "person from America" (in the UK)-- and, needless to say, it's mostly used by Russian-speakers who don't consider themselves ethnically and/or politically Russian.
ЗЗЫ: But, as far as I know, some Russians will use "москаль" in an ironically positive way -- similar to "Why, yes, I'm a black gay Jew, and if you have a problem with that, you are cordially invited to kiss my nigger-faggot-kike ass, thank you very much."
