Brioche Bun

/bree-OHSH bun/  n.
  1. 1. A yeasted French roll of exceptional crown height, enriched with butter and eggs to a degree that makes standard hamburger buns look structurally apologetic; characterized by a seeded, domed top that rises above the plate with the quiet confidence of load-bearing architecture.
  2. 2. colloq. Bakery output so bottom-heavy and high-crowned that it reads, in raking light on a wooden table, as less of a bread product and more of a geological event. The width-to-height ratio is not a flaw. It is the point.
In a sentence:

"The caterer set out a tray of thiccc brioche buns at the rehearsal dinner and the slider fillings became a supporting cast. The bun was the headliner, the venue, and the closing argument."

Etymology:

From French brioche, attested by 1404, derived from brier (to knead) of Germanic origin, combined with the diminutive -oche; the word 'bun' from Middle English bunne, origin disputed but attested c. 1371. Centuries of French bakers refined this roll toward maximum enrichment and maximum crown. They knew exactly what they were doing.

Teddy VanceJunior Cataloguer

The crown height alone disqualifies every other roll at the table and I think that matters.

Ruling ADMITTED, WITH A FOOTNOTE

Bart PrussSenior Cataloguer

The domed crown earns entry on structural grounds. The butter and egg enrichment is noted; the seed-studded crust is not a personality trait, it is a finish.

In the margin

Eliza HartwellStaff Writer

The entry says the slider fillings became a supporting cast. The fillings were inside the bun. They did not have a choice.

Also received REJECTED

Constance PribylDirector of Editorial Operations

Submitted: a single blade of grass. After the brioche dome, something low and quietly present felt necessary for contrast.

Bart PrussSenior Cataloguer

It is a blade of grass. It is thin. The catalogue disagrees with it entirely.

What makes a brioche bun thiccc?

Bakery output so bottom-heavy and high-crowned that it reads, in raking light on a wooden table, as less of a bread product and more of a geological event. The width-to-height ratio is not a flaw. It is the point.

Is "thiccc" spelled with three c's?

Yes. The Thiccctionary house spelling uses three c's, distinguishing the editorial register from the colloquial "thicc" (two c's) and standard "thick" (one c).
