To excel or surpass all competitors, to be the principal in a body or society; an allusion to the fore horse or leader of a team, whose harness is commonly ornamented with a bell or bells. Some suppose it a term borrowed from an ancient tournament, where the victorious knights bore away the BELLE or FAIR LADY. Others derive it from a horse-race, or other rural contentions, where bells were frequently given as prizes.
