An assortment of dingleberries in a brownielike formation baked at a toasty 405 degrees celsius and served to enemies and friends alike as a practical joke.
John: "DUDE you fed him dingle squares?!"
Darvis: "Yep. All 62 of them."
Nobody likes to hang around boring/dull persons for more than half a sec. Having no squares in your circle means your closest ones' group is interesting, driven and adventurous; you stand out as opposed to fitting in.
"… I wanna be somebody, somebody that's never been
No squares in my circle, best shape I ever been"
