Sometimes I believe JK Rowling deliberately litters her books
with various sexual innuendo. For eg:
1. in book 7, the use of 'Erecto' together with setting up a 'tent'
was classic
2. in book 1, Hermione was panicking about 'there's no wood'
3. in book 3, Ron wanted to see 'Uranus' (Your anus) in one of his
classmate's star charts and was punished for that
