a British term for "one who masturbates". Commonly used as an insult.
A: You're such a wanker!
B: O gosh; how did you know?
Did you know that May is not only The ABC's of Swearing month, it is also Masturbation Month?!
This whole "masturbation is a shameful act for women to partake in" starts when we're really young if you think about. I present you, first, with non-visual Exhibit A: A little boy discovers his penis in the bathtub, starts playing with it, and says, "look what I found!" The response: "Aw, isn't he adorable!" Now for non-visual Exhibit B: A little girl discovers her vagina in the bathtub, starts touching it, and says, "look what I found!" The response: "Oh hunney, don't touch yourself down there. Good little girls don't do that."
From that point forward, until Aunt Flow comes for her monthly visit, girls are terrified of their vaginas. Women, do you remember the first time you tried to put a tampon in? Point made!
If you don't know how to pleasure yourself how do you expect anyone else to be able to do it? Think about it; I'll wait...
