'Gp2x' was a pretty random name, but '2x' sounds a bit like 'tuX'. Tux is the official Linux mascot and a formidable penguin, so 'gpTux' is an appropriate way to mis-pronounce it.
Nah I prefer lubidog's explaination Dirty bloody penguins. Leave them alone for 5 bleeding minutes and they got their wings in their pants, unbelieveable! :angry:
