double entendre: "A phrase that has two meanings, especially where one is innocent and literal, the other risqué, bawdy, or ironic; an innuendo."

[Scarblac]

Yes, but a French reader who sees the French word "cul" (butt) won't realize there is also the word ass in English, and that donkeys are also called ass in that language. It's just far fetched.

[scrollaway]

The innuendo doesn’t work in French.
