Smelly Finger is an attack used by the Dragon Ball character Bacterian. The technique starts with Bacterian reaching for his private area and gathering the bacteria living there. Next he takes out his hand (full with bacteria, visible stench and quickly gathered flys around it) and uses his pointer finger while running towards the opponent and yelling "Smelly Finger!". At first it leaves the opponent in shock, quickly followed by states of extreme dizziness.
