foul riding
Riding which after a horse-race is made the subject of complaint, such as refusing to let a competitor pass, boring him against the rails, &c. Some jockeys are great adepts at this work, and are invaluable to a confederacy as a means, not so much of attaining victory themselves, as of preventing its attainment in others. Of course unless proof of jostling can be given, or evidence of malicious intent shown, jockeyship of this kind is not considered foul riding.
