look up any word, like hipster:
(verb) A crime where a drug dealer befriends a weak, old or otherwise vulnerable person, then takes over their home and uses it as a crack house.
"Cuckooing is a new type of crime which involves a drug dealer befriending a vulnerable individual who lives on their own.

Like a cuckoo, the dealer moves in, takes over the property, and turns it into a drugs' den."
