I may have used it once or twice as a joke, but it's not a rating I ever use because something here has made me angry. I think it would be more productive to use the "log out" link for that.
I use the angry frube to show my displeasure at an external link that i find displeasing.
Example Texas - Terrible abortion law doing what Republicans said it wouldn't do
7 of the 11 frubals on that OP are angry
