Swimming while high on marijauna.
Originally a fictional plant from Harry Potter and the Goblet of Fire, gillyweed is commonly used as a placeholder for cannabis in Harry Potter fanfiction.
Girl, I got so stoned last night at the beach, I decided to gillyweed. Water felt amazing but I had major dry mouth after from sweating.

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!!!!
