They are called the Springbok Nude Girls, not because of the gazelle the Springbok.
For many years in South Africa, there was a radio station called Springbok Radio. In the 1980s they had a Top 40 popular music countdown on Saturday afternoons. They also released compilation albums every now and then with the most popular music from their Top 40. This was at that time one of the only stations young people could listen to, and they played Top 40 music from Europe and the USA.
Some Springbok Radio compilation album and tape covers featured a half nude and voluptous gold, silver, metalic, etc. female robot. It was a clever marketing strategy for their compilation albums in a time of strict censorship.
The sexy robot girls became known as the nude girls of Sprinkbok radio.
So the band's name is a throwback to those times, and the now defunct radio station.
