Snot is an euphemism for mucosal discharge. Mucosal discharge has several duties. First, it lubricates the nostrils and sinus cavities. Second, it's the bodies defense against foreign objects from dirt and pollen to large objects like erasers and such that find their ways into nasal cavities. The mucosal discharge traps the foreign objects and through cilia travels forward out the nostral or down the throat. That is where sneezing and coughing come into play.
