What does cuckooing mean?
Cuckooing names the practice of taking over another person's home by force, manipulation, or coercion in order to use it for criminal activity — most commonly drug dealing. The term derives from the behaviour of the common cuckoo, which lays its eggs in other birds' nests and lets the unwitting hosts raise its young; by analogy, offenders occupy a vulnerable person's property while the rightful occupant remains, often intimidated or exploited. Since the rise of 'county lines' drug networks in the United Kingdom, cuckooing has become a recognised term in policing, journalism, and legislation, typically targeting elderly people, people with addictions, or those with learning difficulties. Victims may be effectively trapped in their own homes, and safeguarding agencies treat cuckooing as a form of exploitation rather than a mere tenancy dispute.
The criminal practice of taking over a vulnerable person's home in order to deal drugs or conduct other illegal activity from it.

Named after the cuckoo bird that lays its eggs in other birds' nests, 'cuckooing' is now a serious crime in the UK — drug dealers literally move into someone else's home and take it over.

Etymology of cuckooing
The word derives from 'cuckoo', which entered English from Old French 'cucu' and ultimately traces back through Latin 'cuculus' to an imitative root echoing the bird's call. As a verb, 'cuckoo' long meant to repeat a phrase monotonously, and its present-participle form 'cuckooing' carried that older sense before being repurposed. In the 2010s, UK police forces adopted 'cuckooing' to describe drug dealers taking over a vulnerable person's home, extending the metaphor from the bird that usurps another's nest to criminals who usurp another's dwelling.

In British usage, 'cuckooing' has acquired a strong, specific association with crime and safeguarding policy since the mid-2010s, particularly in reporting on county lines drug networks; this sense carries distinctly negative connotations. The older sense relating to the bird's repetitive call is rare and largely historical or humorous.
