A contraction for "Hello, I find you attractive and would like to dance with you, share some drinks with you, and then perhaps have sex with you. Nothing serious, of course, and I doubt that this will result in a long term relationship, but I would appeciate you considering my proposal."
a slang term used in New England in place of a Greeting. Not rude or impatient just used as a neutral greeting to any person regardless of the mood. Used among the youth constantly and seen as rude by older people.
