“to take a French leave” (to leave a party or other gathering without taking polite leave of one’s host) is referenced in French as filer à l’anglaise (lit. “flee English-style”).

In slang, sexual acts and diseases are *consistently* attributed to another nationality. Like in modern American English, you have *French* kissing (and historically, “French letters” for condoms), anal sex is called “Greek” and titty-fucking “Russian”.

IIRC at some point every country in Western Europe referred to syphilis as “The (X) Disease”, where X was a different foreign demonym.
