WGASA
Some years ago, the famous San Diego Zoo opened a second, larger branch called the San Diego Wild Animal Park. The Park is built around an enormous open-field enclosure where the animals roam free. To see the animals, visitors ride on a monorail called the Wgasa Bush Line which circles the enclosure.

They wanted to give the monorail a jazzy, African sounding name. So they sent out a memo to a bunch of zoo staffers saying, "What shall we call the monorail at the Wild Animal Park?" One of the memos came back with "WGASA" written on the bottom. The planners loved it and the rest is history. What the planners didn't know was that the zoo staffer had not intended to suggest a name. He was using an acronym which was popular at the time. It stood for "Who Gives A Shit Anyhow?"

Confirmed as true by the zoo's management, according to Snopes.
