I believe it is in To the Lighthouse that Virginia Woolf mentions two sailors "laughing at a joke that was not at all proper".

Has anyone mentioned the term "bathroom humour"? It's gone out of vogue, but I think it's time we brought it back ....


On another matter - in Canada, "Anglo" is usually encountered as a linguistic descriptor - anyone English-speaking, or English-speakers collectively, may be characterised as "Anglo" (or, more properly but more syllabic, "Anglophone").
