suppressed sneeze

A less-than-freely-discharged nasal-cannon blast dat you create in order to make less mess, reduce noise, not make your respiratory-path so sore, etc.

One of da best ways to accomplish an effectively-suppressed sneeze is to hold a large wadded-up towel over yer nose and mouth while also trying to still your vocal cords as best you can, so dat you both "contain your explosion" and cause a minimum of startling to others in your vacinity, not to mention reducing stress to your throat.
