The usage of the expression "keep care"?

Good afternoon guys

Very recently I read a expression "keep care friend" and it's something that I would probably never say. However as I checked on the internet, I found quite a lot of sites and posts using a similar expression "keep care of" (American ones not British) which doesn't sound as weird as the first I mentioned.

So, I am here to ask you guys about it. Is it correct or wrong? Maybe grammatically correct, but sounding weirdly wrong to your ears.

Thanks in Advance!
