bulling:

Bullying is the intentional tormenting of others through verbal harassment, physical assault, or other more subtle methods of coercion such as manipulation There is currently no legal definition of bullying.
In colloquial speech, bullying often describes a form of harassment perpetrated by an abuser who possesses more physical and/or social power and dominance than the victim. The victim of bullying is sometimes referred to as a target. The harassment can be verbal, physical and/or emotional.

It is only in recent years that bullying has been recognised and recorded as a separate and distinct offence, but there have been well documented cases the were recorded in a different context. The Fifth Volume of the Newgate Calendar contains at least one example where Eton Scholars George Alexander Wood and Alexander Wellesley Leith were charged, at Aylesbury Assizes, with killing and slaying the Hon. F. Ashley Cooper on February 28, 1825 in an incident that would now, surely be described as "lethal hazing". The Newgate calendar contains several other examples that, while not as distinct, could be considered indicative of situations of bullying.
