人和他做的事：自信滿出來
這一支最貼近核心畫面：把音量開到最大的是一個人，或是他當下做的那件事。

Behaving with too much confidence, talking too loudly, and not seeming to care how the people around you feel. The word shows that the speaker does not like this.

核心畫面
Picture something with the volume turned up too high. A person walks in talking loudly and does not notice the room. A wall is painted a yellow you can see from the bus stop.

brash 可以想成「音量被轉到最大」的那種感覺。有人一進門就講得很大聲，沒察覺房間裡的氣氛。有面牆漆成從公車站就看得到的黃。有個決定在別人來得及說「等一下」之前就做完了。這三件事在英文裡共用同一個字：太多、太快、沒有柔和的邊。而說這個字的人，通常不太欣賞眼前的東西。From the word’s history
Wiktionary marks the origin as uncertain, and offers a possible link to Scots brash, meaning a violent onset or an attack, with a further family resemblance to German barsch and Danish barsk, both meaning harsh or rough.
維基詞典說這個字的來源並不確定。它提出一種可能：來自蘇格蘭語的 brash（猛烈的衝撞、攻擊），並且可能跟德語 barsch、丹麥語 barsk（粗硬、不客氣）同一家。因為來源本身就標著「不確定」，所以這只是一條參考線索，不是定論。

東西：用顏色和體積在喊人
東西不會講話，可是它一樣可以很大聲——把「音量」換成顏色、亮度和體積，核心畫面就成立了。
