It is a woman's name that surely comes from a hypocoristic in English for compound names (such as Jane Valerie or Julie Victoria) by its initials "JV", which in Spanish sound similar to 'yei vi'. Also in slang is an adjective associated with initials as a woman's name, but in this case for jealous vagina, "a toxic girlfriend who does not allow her partner to have female friends or to go out in groups where they are".
