All that, and no mention of wazzock, probably my favourite mild insult and relatively unheard it would appear (it was was quite popular in parts of the UK's north in the 80s & early 90s but I don't think it travelled internationally and has since largely fallen back out of use even here). It works particularly well with the common extension "great steaming" as a phrase of exasperation: "you great steaming wazzock" (for full effect: say slowly, in one sighing breath, emphasising each word more than the previous, and take a deep disappointed breath after).
