I've been a climber for a long time and have not heard the term "screaming barfies" used in that sense. I've always heard it from ice climbers to describe the nauseating sensation of regaining sensation in frozen hands as they unthaw. But maybe the use of the term has expanded.
You beat me to it!
I've been ice climbing for 25 years and you have it absolutely right. I have never heard that term used in any relation to rock climbing. Can be your toes as well, but regardless, it hurts like hell and you do feel like you're going to hurl massively while it's happening.
