Underpants (Australian Slang). May be acceptably abbreviated to "durps".
Crikey mate, I haven't changed me underdurps in a week and the blowies are hangin' round me arse.

Translation: "Oh my goodness, sir. I have neglected to replace my underpants in seven days and there are flies surrounding my nether regions."
