grundies 

(Australian): Underpants.

Derives from Sydney Rhyming slang, "Reg Grundies = Undies", which is a reference to that excellent Australian TV production outfit Reg Grundy, behind such televisual classics as Neighbours, Home and Away, The Sullivans, etc.

From "The 12th Man Again", wherein commentator Max "Tangles" Walker discusses the perils of prolonged bouts of commentating on international cricket competitions:

"when you're sitting around in the commentary box for this length of time, it's not unusual, really, for the old cods to maybe nod off, get a bit numb; I think the best thing to do in situations like this is to get up, stretch the old legs; maybe even try to casually slip the old hand down and, maybe, give them a bit of a rub; probably try and adjust the old reg grundies while you're down there; try and loosen them up a bit. Anything, really, to try to get the old circulation going again."

Gunde 

A nickname often given to the baddest motherfucker in your posse. You will usually find him in his lifted, piped out pickup truck chasing ugly women and shitty beer. This is a man you do not fuck with.

Gunde is the fucking shit, love that guy.

pidge gunderson / katie holt

pidge is the green paladin and pilot of the green lion from voltron: legendary defender. she has short dirty-blonde hair, brown eyes, and glasses. she disguised herself as a boy so she could get into an elite space school called the galaxy garrison in order to hack into their systems and discover encrypted information about the mission to a planet called kerberos that her dad and brother had been a part of. the news reports said everyone had died but the information she found after hacking the school's system said otherwise. they kicked her out of the school under her birth name, katie holt, after she was caught hacking once. she changed her name to pidge, the nickname her brother had given her, to get back into the galaxy garrison as someone else. pidge is a smol bean, an icon, a legend, and a badass. she's also a pretty good pilot.

gunder 

(noun) A liquid drink served at the Phi Psi lodge at Cornell University especially during the 1970s. Used as a substitute for other decent drinks in order to save money for the house. Gunder was akin to Kool-aid, but somewhat thicker. It did not come in flavors, so much as it came in colors of which there were primarily two -- green and red.

The Brow's skin tone was the color of green gunder. Red cake goes well with a big glass of green gunder. My blood flows with green gunder.
