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.

Grunderpants 

Underwear soiled with fecal matter, having skid marks or filthy from bodily fluids such as semen, urine, vaginal secretions or ass sweat.

I just sharted. I’m gonna have to walk around with grunderpants all day.

She pulled her panties over my face. While expecting a fragrant experience, I got grunderpants and a big skid right across my nose.

I sniffed her grunderpants and it was a whiff of stank ass booty juice.

gunderson 

An insulting Jersey Shore name for tourists from the Midwest, especially those who are naive or who have never seen the ocean (or Atlantic City) before. This term likely evolved sometime after the release of the movie Fargo, which featured a major character named Gunderson.

Hey, check out that gunderson staring at the Borgata Babe.

Grunders 

Underwear worn more than a 24 hour period of time by either a male or female. Underwear become Grunders after they are worn more than 24 hours or they are soiled and stained from urinary or anal leakage. The hallmark of turning your undies in to Grunders are those that are accentuated by skids and skid marks and mud marks.

Leroy was so behind in his laundry that he ran out of underwear. He ended up wearing the same pair for over two days. He finally did a load of whites after dropping skid marks in his Grunders.
