Words you can keep
A cannibalistic fish who eats anything and everything (even other fish) to have a big home all to herself.

Eeek!
There were several fish in the fish tank living with Gillyweed. Then all of a sudden there was one less fish. And then another disappeared. And finally, the last fish living with Gillyweed was found severed in two; head and tail were found floating at the top of the tank. And Gillyweed just got bigger and bigger.

Don't be a Gillyweed! Cannibalism is BAD!!!!

Word of the Day on August 25, 2026
West Midlands slang word for rockers, bikers, greasers etc. In the late 1980s it was used by the UK music press to refer to a specific scene centered around the bands Pop Will Eat Itself and Crazyhead. The term never found favour with readers of 'the inkies' (Sounds, Melody Maker and the still extant NME) and was soon dropped. Now often used in predominantly working-class areas of the midlands and the north to mean someone who listens to rock-derived music and/or dresses in a manner that suggests they affiliate themselves with rock music of some kind.
