Could have been quite a tirade. Putin is no doubt fluent in Mat
("Mat (Russian: мат, матерщи́на, ма́терный язы́к) is a Russian patois language, based on the use of specific generally unprintable obscene words. Russian mat makes it possible to have a conversation (although not always insulting, but always emotional) using only obscene words, which is what sets Russian mat apart from the obscenities of most languages.
Russian mat is an indispensable attribute of any group consisting solely of males, only recently beginning to get into the females-only groups, and the practices of mat speaking in the mixed groups are to be reduced to the last twenty or thirty years. [1] . Use of Russian mat in a public place constitutes a form of disorderly conduct, punishable under article 20.1.1 of the Offences Code of Russia.")
It is commonly believed that the name mat derives from mat′ (Russian мать, "mother," where the prime represents the soft sign, which signals palatalization of the preceding t).....
The basic formula of mat, in its most common variant, is: YOB TVOYU MAT'
Untranslatable on FR, except to say that "TVOYU" means "your".
