A "Bitchin' Betty" is an aural awarning system. The TAWS B systems have it. It calls out "Terrain, Pull Up... Terrain, Pull Up".
The AOA system (Precise Flight, I think?) that WS and many others are using in their RV's have an Aural warning too. Those systems bitch, "Angle, Angle... Push, Push..."
I love this stuff and want to put things like this in my plane!
Hey, you got today (Columbus Day) off? Working on your plane?
I am going to the airport to install some lights at the FBO. My buddy wants some ramp lighting. Fortunately, it is the INSIDE work I plan on doing today. TORRENTAIL here still!
I wish I was working on MY plane!
