Used to call out a cadence as for marching.
Hup is defined as what someone shouts repeatedly to command a group of people to march in rhythm.
An example of hup is what an Army drill instructor says to call the marching rhythm for his soldiers.
The first beat of a 4/4 military cadence, commanding either the lead-off step in a march or some other action.
After four we raise our swords...One Two Three Four...Hup Two Three Four...Hup Two Three Four.
