I’d like to verify a claim found on several platforms, with regards to sexual innuendo in the movie "The Goonies".
The website states the following:
The boys are looking for the treasure of One-Eyed Willie. “One-Eyed Willie” is a name for a penis. The fact they are looking for his treasure indicates they seek a positive relationship with their penis, which has been conditioned to be surrounded in shame and confusion.
This claim seems to be supported by other unofficial sources, like Urban Dictionary (where anyone can add a random definition of a word), Reddit (another random claim) and many others. This is a list published on Quora and here there is an extensive research on the term "willy" but only a single mention of "one-eyed willy", which does not cite any source whatsoever.
I'm not a native speaker, so I can only check the usage of this expression based on the English corpus. This is the result from Ngram:
Using english-corpora.org resulted in barely 50+ mentions of "one-eyed willy" and none seems to be used as a reference for penis.
Is this a made up definition or is there any truth to the sexual innuendo?
