When the San Diego Wild Animal Park opened in 1972, it featured a monorail that visitors could ride around the park’s perimeter. The railway was called the Wgasa Bush Line, a suitably exotic name that many visitors assumed was African.

In fact the name arose in a planning meeting. When chief designer Chuck Faust couldn’t think of a name, he wrote WGASA on the plans. “Everybody laughed because they knew what it stood for, but they loved it because it sounded African,” zoo founder Charles Schroeder wrote later. “We thought WGASA would blow over, but it actually stuck.”

It stands for “Who gives a shit anyway?”
