Hi guys, I discovered what is for me one of the best lub i ever bought: "Boy Butter" (the other best one would be "Astroglide Lub". But one day i was watching an episode of the Family Guy Season 10 ep. 7
A butter churn is very much a real tool, and is how butter was made on a small scale (i.e. not in a factory). The internet is chock full of information about them, so I cannot comprehend why you couldn't find anything. They come in both rotary and plunger styles. The rotary types are still used by some cooks who prefer to make their own fresh butter. The plunger style is largely an artifact of a rural past, as it was easier to build than the rotary type, but takes more effort to operate. In either type, a part called a dasher churns the cream, which causes the butter to separate. The plunger style (as pictured on the Boy Butter label) is operated by working the dasher handle up and down, in and out of the hole in the cask, for a long time. The association with sex, or at least masturbation, is obvious, particularly given the cream. (Indeed, if you keep fucking hard after you have produced your own cream, you just might produce some butter in the hole, or at least whipped cream, in my experience.)

BTW, If you chill a rotary-style butter churn, and fill it with a cream and flavoring mixture, you can make ice cream instead of butter.
