Question for our British friends

[AoTFan]

Dunno if we have any on this board, but I'm sure SOMEONE will know this...

In general, what "level" of insult is "wanker"?  

I mean, is it a mild one like "goofball" or "dummy", bit more serious like, "jerk" or "idiot", or maybe a mild swear word territory like "a***ole"?

[Alex]

Mild swear. Jerk isn't really one that is used in the UK, but idiot would be a kids playground insult (say under 12). Once you get to your teenage years you'd be more inclined to call someone a wanker and it cause offence. By the time you are an adult, you'd be more likely to laugh and say "Yeah, you telling me you don't?"

[Trevor]

The Afrikaans version of that word is "draad trekker" [dhraad trekker] meaning wire puller 

[Allhallowsday]

"Wanker" is the same as "Jerk off" or clinically, "masturbator". 

[dean]

Depending on context in Australia it can even be a term of endearment (albeit rarely).

We all have 'f**k!' in common!
