1.
peeping (Tom); voyeurism (illegal act of secretly watching someone)
The act of secretly watching someone — typically through a window, gap, or small hole — especially in a sexual or invasive context. Used as a legal and news term for the crime of voyeurism, and also as a noun for the person who does this (a 'Peeping Tom').
2.
a peek; a quick glance (neutral sense)
A brief or partial look at something through a small opening or from around a corner. Neutral usage, often appearing in compounds like 覗き穴 ('peephole') or 覗き見 ('a peek').
The noun form of the verb 覗く ('to peek; to peer in'). Meaning shifts sharply depending on context: in crime/news contexts it refers to voyeurism, while in neutral contexts it simply means 'a peek' or appears in everyday compounds.
Usage
In isolation, especially with verbs like 働く ('to engage in [a bad act]') or 被害にあう ('to be a victim of'), it almost always carries the voyeurism sense. In compounds such as 覗き穴, 覗き見, or 覗き込む-related contexts, the neutral meaning is normal.
