Thickheaded,
I was just trying to get in on the conference thing she had going on Instagram, and some guy was trying to attach his video connection to things. I only saw about two seconds or so, and couldn't tell what the hell was going on. The lighting wasn't great, and too dark from the guy's video feed. But based on what video feed Linda and her two girlfriends (they were in on another segment of the video feed) saw (that wasn't connected to the public viewing I had that continued after his segment was cut off from the public viewing), the guy was apparently masturbating in full view of them.
The overall video feed then ended just about two minutes later, and Linda signed off.
That's the gist of what they were saying/meaning.
