Though being of Scottish decent, I've not lived in Scotland, and as such I'm not familiar with all the terms and remnants of Galic in day to day Scottish. But a friend of mine, she's as pure as they come. She claims its a rather old term for "glad to make your acquaintance/how do you do?". With anything Galic (not being a written language) spelling is always an issue. I see that its more often spelt Foos yer doos.
If you go back. The Namib desert is beautiful, and very different north to south. South coastal regions are red (like the Kalahari, where the sand in fact comes from - long story). Aroudn Sossous and dead vlei the dunes are massive, the biggest in the world (up to 450m tall). The locals thought we were mad when we northerners started climbing them midday at 50C. Fiurther north lesser sand dunes, and then gravel towards the diamond coast. The Naukluft mountains and the Fish and Zebra River canyons are fantastic. Etosha is nice, but I rather prefered the landscapes further south (being a mix of Norwegian and Scottish must have something to do with it).
