Cussing is when you try to insult someone, eg. Your mum.
Cussing isn't even a word. Swearing is a scientific term, too.
Dysphemistic swearing - Exact opposite of euphemism. Forces listener to think about negative matter. Using the wrong euphemism has a dysphemistic effect. (Example: He forgets her!)
Abusive swearing - for abuse or intimidation or insulting of others (Example: You motherloving son of a bitch! forget you, starfish!)
Idiomatic swearing - swearing without really referring to the matter.. just using the words to arouse interest, to show off, and express to peers that the setting is informal. (Example: forget, man.)
Emphatic swearing - to emphasise something with swearing. (Example: It was so loving big I swear!)
Cathartic swearing - when something bad happens like coffee spilling, people curse. One evolutionary theory asserts it is meant to tell the audience that you're undergoing a negative emotion. (Example: Aww, forget!)
I do idiomatic swearing.
