When I saw this photo of Billie Jean King and Snoop Dog at the Olympics, I finally had to investigate and clarify of the meanings of two fingers raised. I do understand that it is considered to be a positive sign, meaning something like Rock On, but it was once something different in my my personal memory.
We'll get back to the Rock On salute later, but I first, I began with search about the typical one-finger salute. We all know what it means, more or less anyway.
The obscene gesture made by holding only the middle finger of a hand erect while the rest of the fingers are in a fist. (Wiktionary)
Then, I searched to reaffirm the meaning of the English two-finger salute. I already knew this but wanted to be clear.
The "two-fingered salute" ... is commonly performed by flicking the V upwards from wrist or elbow. The V sign, when the palm is facing toward the person giving the sign, has long been an insulting gesture in the United Kingdom, and later in Ireland, Australia, New Zealand and South Africa. (Google)
Here is a little more information about the origins. Although there seems to be some doubt about the origin of the tale, I choose to accept it because I like it.
A commonly repeated legend claims that the two-fingered salute or V sign derives from a gesture made by longbowmen fighting in the English army at the Battle of Agincourt (1415) during the Hundred Years' War, but no written historical primary sources support this contention. This origin legend states that English archers believed that those who were captured by the French had their index and middle fingers cut off so that they could no longer operate their longbows, and that the V sign was used by uncaptured and victorious archers in a display of defiance against the French. (Wikipedia)
This up yours two-finger sign is not to be confused with the V for Victory sign. In the Victory version the palm faces away from the person using it. The other, nasty version has the perpetrator's palm facing inward.
With his palm facing outwards, Winston Churchill flashed the V for Victory sign.
Finally, I got onto my primary mission of trying to resolve the positive Rock On interpretation with how it conflicted with my boyhood understanding.
It was back in my childhood, Montreal days that I had understood this two-fingered gesture to be very offensive. However, I don't think I have seen anyone using it after moving to Ontario at the age of fifteen. Here, it has always been the typical one-finger salute. Sue, a Toronto and Ontario girl, has never known of my two-finger variation, which I just described to her. She only knows the Rock On vibe.
Was I misremembering? Perhaps it was that, or perhaps, it was just a gesture of the boys of my school and neighbourhood? What would an online search reveal? I found that it is a gesture with a meaning other than Rock On.
The sign of the horns is a hand gesture with a variety of meanings and uses in various cultures. It is formed by extending the index and little fingers while holding the middle and ring fingers down with the thumb. (Wikipedia)
Wikipedia followed with a little more information.
In many Mediterranean and Latin countries, such as Colombia, Greece, Italy, Portugal, Spain and Mexico, when directed towards someone, pointed upward, and/or swiveled back and forth, the sign offensively implies cuckoldry in regard to the targeted individual . . .
I am not sure why that manifestation also occurred in English Montreal in the fifties and early sixties, but it certainly did. Did the francophones also use the symbol? I expect so, but I don't know.
After my little bout of research, I now know, or at least think I know, the meanings of these gestures in their various contexts. Why it has taken me this long to really delve into the topic, I know not, but I am content to have resolved it at last. It still perplexes me why that one variation was so prominent in the Montreal of my boyhood, but at least I am pretty well assured that I wasn't mistaken.
