AHD A double entendre, most of the time, is not used as a replacement, but in and of itself. That is, the writer or speaker chose the word(s) specifically
because it would have a double meaning. I finally thought of an example: a man is recounting a visit wherein a buxom woman showed him her garden, and he says, "She has great cantaloupes". Had he not wanted to make the joke he might have simply said she has a nice garden.
