OK, my brother reminded me what I remember slimy okrie from.
My mom used to make sloppy joes by browning the hamburger and putting in a can of chicken gumbo soup.

EEEEWWWW. Of course there were slimy little things in it which is what I remember the most. That was the only okra I remember until about a year ago when I discovered I liked it when it wasn't slimy.
