Yes and No
The word JEVITOS was used to define teenagers from well off families back in the late 80's, the true rich, old money. Back then, these jevitos did flock to Lincoln Ave AND where in fact kids from well off families sporting the latest cars. BUT, nowadays, the media is using the word wrongfully as those partying at the avenue are nothing more than a bunch of CHOPOS that can't get into one of the hip bars and clubs. The TRUE JEVITOS don't care for Lincoln Ave. anymore. These chopos partying at the avenue who in fact drive bmw's and the like (rarely as Acura and HONDA are their preffered brands), usually come from medium to low class sectors, and those whose families might have money have made it from politics and/or other get-rich-quick schemes thus not entitling them to be called JEVITOS.
