What does the expression "to shine someone on" mean?

to shine someone on, as used in Terminator 2 by John Connor (Edward Furlong) he goes on to say that "it's hasta la vista, baby", which in a literal translation says "until the view, baby" and more loosely means "until i see you again", baby. So what he's getting at is this: to give someone the impression that you're attracted or into them, but they will have to wait and see, you say "Hasta la vista, baby". So, by using the spanish farewell in a conversation in English he's acting cool, like. Right? Thus, he is "shining" them on.

So a similar thing would be to string someone along or to lead them on.

I think is to avoid someone.

The overall attitude of someone that shines you on is to appear to be interested in order to pacify you.
The intention is the hope that in doing so that will keep you off their back. Feign agreement when not really agreeing.
Feign being friendly when not really being a friend.

Holy moley!

Saw this in my feed and thought that Kicky was back.

Oh, well!

Hope he is enjoying Florida.

I always thought it meant to "champion" someone's talents or efforts.

"Hey, I'll have your money on Tuesday. Had it yesterday, but I couldn't find you!"

If you shine someone on, you are getting rid of them as quickly as possible.
