A Kush up is a very small hit of a joint. Experienced people in Kush ups can do multiple at a time. For instance 30 Kush ups = 30 continous small hits without blowing out the smoke, only at the end you are allowed to breathe again.
Hey bro i challenge you to do 20 Kush ups.
Alright man *does the hits*
