ride

   1. to copulate with

   Usually of a man, with the common equine imagery:

    You ride like a kern of Ireland, your French hose off. (Shakespeare, Henry V)

   but also of a woman, especially if above the man:

    Gabby groaned as she rode him at a little under a canter. He lay easing himself up to her. (L. Thomas, 1979)

   A ride is either a female viewed by a male for copulation, or the act:

    Reckon you'll count it a pretty dear ride you had, friend. (Fraser, 1971)

   and, at least in Dublin, it may mean a male so perceived by a female:

    Anita shouted after him. — Mandy said you're a ride, Darren! (R. Doyle, 1991: the demure Mandy denied this: 'I did not, Anita. Fuck off.')

   To ride St George was to copulate with 'The woman uppermost in the amorous congress, that is, the dragon upon St George' (Grose). It was said to be the best way to beget a bishop.

   2. obsolete Scottish

   to be a thief or marauder

   The language of the Borders, where riding out or riding and robbery were almost synonymous:

    Ride, Rowlie, hough's i' the pot. (Nicholson and Burn, 1777 — hough was the last piece of beef, and it was time to rustle some more)
