мент

Policeman, the fuzz — quite often used, if police officers are out of earshot. Loaned from Polish, where mente has been used as slang for soldiers or guards (initially it is a Hungarian word for a short coat-cape, also called “fur attila” that was part of policemen’s uniform).

У ментов маленькая зарплата, но хорошие доходы.

Coppers have small salaries but comfortable income.

Ментам писькой по губам (“Hit cops with dicks on the lips”),

A cop was born (said when sudden silence appears).

— Мент родился, — прокомментировал Никита тишину, но она вдруг снова нарушилась: на сей раз посторонним шумом с улицы.

(Евгений Козловский, Гувернантка)

1. Police car, also called ментовоз; 2. the fuzz, police.

Вдруг её остановят, проверят документы, препроводят в ментовку и запрут вместе с проститутками.

Suddenly she is stopped, ID check, she is transferred to the nick and locked up with the prostitutes.

(Виктория Токарева, Своя правда, 2002)
