Translation guide
The English abbreviation "BS" can refer to "bullshit" (nonsense, lies) or "Bachelor of Science" (academic degree). This guide covers both meanings, focusing on natural Japanese expressions for each context.
Expressing that something is untrue, exaggerated, or meaningless, similar to the slang "bullshit".

Referring to the undergraduate degree Bachelor of Science.
The formal Japanese term for a Bachelor of Science degree. Often abbreviated as "理学士" in contexts where the field is clear.
彼は理学部で学士（理学）を取得した。

There is no direct Japanese equivalent for the slang "BS." Translating it literally as "bullshit" (雄牛の糞) would be nonsensical. Instead, use context-appropriate words like 嘘, でたらめ, or 大げさ depending on the nuance.
彼の言うことは全部でたらめだ。
Everything he says is BS.
嘘 (uso) is a straightforward lie or falsehood. でたらめ (detarame) implies something is random, unfounded, or nonsensical. Use 嘘 when someone is intentionally lying, and でたらめ when something is just made-up or baseless.
彼は嘘をついた。
