(It’s about vernacular masturbatory verbs, so it’s deemed not suitable for kids, and of course it’s not to the taste of the sexually modest.)
Why would anyone care whether a guy favors jack off or jerk off — or something else, like jag off or toss off or wank — as his masturbatory verb?
Street talk about sexual practices and unsavory bodily substances varies over time and place and context, differs from one speech community to another, just like all kinds of talk: wank and toss off are distinctly BrE, jag off distinctly AmE, and jack off and jerk off both seem to be originally AmE, though they’ve spread more widely; guys will have different preferences for vocabulary in this domain, mostly according to their personal experience with the verbs, and they’ll know that some guys use different verbs. Why doesn’t it stop at that?
Well, this is linguistic variation, and it pretty much never stops at that. There’s a general human inclination to believe that your own practices are the best ones, the right ones; and also a general human inclination to accept the practices of your community, which are likely to be supported by explicit teaching and advice, and even enforced with sanctions, as the best ones, the right ones.
So we find people deploring other people’s linguistic practices, often in extravagant terms (disgusting, ignorant, …), sometimes ascribing dubious or discreditable motives to other people’s choices (hypercorrection and varieties of avoidance are often cited, as are faddism, reflexive following of fashion, and misguided attempts to sound clever). Even for masturbatory verbs, where there’s no explicit teaching and no advice literature.
Now, one such example, in a recent Facebook exchange between Jeff Shaumeyer (a jerk-off user) and me (a jack-off user), which turns out to be surprisingly complex, because it involves a second-order effect, with responses to (first-order) critiques of the usage jerk off, that it’s too crude, too vivid (the imagery is of the jerking motion in masturbation, and in the jerking of the body in orgasm — jerk was used for ‘copulate with’ before it was extended to masturbation, and is still so used by some speakers). This critique has led to the idea that guys who use jack off do so (only) because they’re (fastidiously) avoiding the gutsy, authentically masculine jack off — a gratuitous attribution of motives that I stringently objected to.
