avere la scimmia means: Italian phrase meaning “to have the monkey in order to get the monkey.” This expression is typical of youth slang. There are two main meanings to it. 1. To be obsessed with someone or something or desire something very strongly. The reflexive verb “inscimmiarsi”, which can literally translate to “to be “inmonkeyed”, is also used in the same sense. The expression can be used to indicate that someone is addicted or suffering withdrawal symptoms from a drug. 2. A bad mood, or a general feeling of being in an unnatural or specific but difficult mood. (in Community Dictionary, added by Lourdes Márquez)
