A rare species of animal, native to Tasmania. Squilliams walk on 4 legs but are able to sit upright, similar to beavers. However, their walking capabilities are limited when on 2 legs. Squilliams saw vast brutality and oppression following British colonization of Tasmania, and later through their unfair treatment by the Australian government.

Before British hegemony fragmented and destroyed the Squilliam's way of life, they lived free in the vast forests and grasslands. However, following British colonization of Tasmania in 1803, their habitats were destroyed and many Squilliams were hunted down for their expensive furs. The result was brutal fighting between British colonizers and guerilla tribes of Squilliams, armed with whatever they could find. At first, the less-equipped Squilliams struggled with their oppressors, who wielded advanced firearms and horses. However, Squilliams were able to make use of their habitat, which the British colonizers were not familiar with. The British government was no match for these ravenous beasts and were forced to withdraw from the sporadic fighting. Today, Squilliams can once again live free in their homeland and graze on the rich grasses of Tasmania, free from British oppression.
"I'm a fan of Squilliam meat personally, though it is a bit too gamey"

My boyfriend's penis. First name Squilliam, last name Scrotum. Resembles Squilliam Fancyson's nose from Spongebob, in length and in girth. I would call him Squidward, but Squilliam is obviously better.
"I can't wait to get home and play with Squilliam. Gonna have so much fun! "

"Oh, who's Squilliam!? Did you get a new pet?"

"No. Squilliam is my boyfriend's dick."

A guy who acts like he’s all sweet and kind and won’t ever hurt you and then stabs you in the back and wants to “be friends” because he doesn’t want to commit to anything. Usually someone talked him out of it because he can’t make decisions for himself. They typically need therapy. Squilliams say weird things like Dandy, Swell, and Hashbrown a lot
Girl 1: UGHHH, I cant believe John broke up with me!!!
Gril 2: HE IS SUCH A SQUILLIAM!!

In the TV show, Spongebob Squarepants, Squilliam is Squidward Tentacles' rival who made millions of dollars doing what Squidward wish he could do. Squidward always tries to impress him and usually ends in an epic fail excluding the episode where Squidward had a band.
I need a 5 diamond restaurant because I told Squilliam Fancyson that I run one!!!

A very weird person. You can usually find them in a cave, crawling towards you growling and making weird noises, eating anything they find on the ground, or running around like they are on crack. But all in all they are a fun person to be around and you are lucky to know one.
Hey yesterday I met the weirdest person.
Hey it must have been a Squilly Squilliam
