Spitting is the act of forcibly ejecting saliva, sputum, nasal mucus and/or other substances from the mouth. The act is often done to get rid of unwanted or foul-tasting substances in the mouth, or to get rid of a large buildup of mucus. Spitting of small saliva droplets can also happen unintentionally during talking, especially when articulating ejective and implosive consonants.
Spitting in public is considered rude and a social taboo in many parts of the world including the West, while in some other parts of the world it is considered more socially acceptable.
Spitting upon another person, especially onto the face, is a global sign of anger, hatred, disrespect or contempt. It can represent a "symbolical regurgitation" or an act of intentional contamination.[1]
