How is it used?:
Gary married Nancy and the next thing you knew he was the most pussy-whipped guy you ever saw.
What does it mean?:
Usually heard and seen as "pussy whipped" or "pussy-whipped," "pussy wipped" may be either a new variation or a misunderstanding. Used as an adjective to refer to a male who is under the thumb of a female. Concluding that the female grants the male sexual favors can be a misstep; however, that is commonly assumed.
"Whipped" by itself is used to mean "extremely obedient to one's significant other," according to The Online Slang Dictionary (http://tinyurl.com/ysw8w4). That's likely to be a recently coined egalitarian usage.
How did it come to be used this way?:
The Online Etymology Dictionary (http://tinyurl.com/37s23u) says "pussy-whipped" was "first attested 1956," but that seems to be far too recent. Check with some older gentleman (say in his 80s or 90s) and he may tell you he heard the term used when he was a teenager, perhaps in the 1920s or 1930s. The term is so obvious, it could well have been around for decades by then.
