Here is some Cambridge University slang from the eighteenth century:
TO CUT, (CAMBRIDGE). To renounce acquaintance with any one is to CUT him. There are several species of the CUT. Such as the cut direct, the cut indirect, the cut sublime, the cut infernal, etc. The cut direct, is to start across the street, at the approach of the obnoxious person in order to avoid him. The cut indirect, is to look another way, and pass without appearing to observe him. The cut sublime, is to admire the top of King's College Chapel, or the beauty of the passing clouds, till he is out of sight. The cut infernal, is to analyse the arrangement of your shoe-strings, for the same purpose.
I have done all four of these, but never knew that there was a name for them.
Sorry, I didn't see you there.
