push

   1. (of a male)

   to copulate with

   The usual thrusting imagery but also from the rhyming slang, a push in the truck:

    'You pushing her?'... 'Every chance I get.' (Sanders, 1970 — the lady was not confined to a wheelchair)

   Whence, in West Africa and perhaps elsewhere, push, copulation:

    Sing, dance, cook, plenty push. (Sanders, 1977 — a female servant was being extolled to a bachelor)

   2. (the) peremptory dismissal from employment

   Given by the employer. Seldom of an employee leaving of his own volition:

    It is conceivable that not all employees relished the chance of encouraging ambitious young men to give their firm 'the Push'. (E. S. Turner, 1952)

   3. a sustained attack in war

   Jargon from the Second World war:

    The gen is that the jerries are preparing a push on Alam Haifa. (Manning, 1977)

   4. to distribute (narcotics) illegally

   Literally, to sell energetically or fraudulently, as with a share pusher who sells securities at false values. A pusher is an illegal distributor of narcotics:

    He was on the weed. I pretended I was a pusher. (Chandler, 1958)
