Italian Handkerchief
An Italian Handkerchief is when you have a runny nose and do not have anything to blow into. You plug your free nostril with a finger or thumb, turn your head to the opposite side, inhale, close your mouth and exhale through the clogged nostril. The offending nose nuggets are then forcibly projected to the ground. Oh yeah - do this OUTSIDE!
Me and my girl were out walking off the quarantine 15 and my nose was running. I did an Italian Handkerchief to clear my nose. Se was appalled! She said "WHAT was THA??!?" I said that "that's an Italian Handkerchief!" She said "That's not a thing!" I said "Check that shit on Urban Dictionary!"
