Translation guide
The English word "necking" can refer to two distinct concepts: a passionate form of kissing and cuddling, and a construction or engineering term for joining materials. This guide focuses on the romantic meaning, which is the most common usage for English learners.
To describe the act of kissing, hugging, and caressing passionately, often in a romantic or sexual context.
A common onomatopoeic term for lovey-dovey behavior, including kissing, hugging, and flirting. It can be used as a noun or a suru-verb (イチャイチャする).
To describe the process of joining two pieces of material, such as metal or wood, by reducing their cross-section or using a necked-down section.
The English word "necking" does not have a direct one-to-one Japanese equivalent. Using a literal translation like 首をすること (kubi o suru koto) would be nonsensical. Always use context-appropriate terms like イチャイチャ or ペッティング for the romantic sense, and ネッキング for the technical sense.
公園でカップルがイチャイチャしていた。
A couple was necking in the park.
Similar to イチャイチャ, but often implies clingy physical affection. Can be used as a noun or suru-verb (ベタベタする).

A more literal description: "kissing and embracing." This is a neutral, clear way to describe the action without slang.
