Seconds Coming back for more?

Choice British Slang

Some words I picked up on that I would love to bring back are:

Knobhead (dickhead), muppet (dumbass), cow (derogatory word for woman), and, bell end (cock).

I'm sure this list will be expanded upon before I leave, but for now, this is what I have. I'm also well aware that some of this stuff only works in a British accent, but c'mon, haven't you always wanted to call someone a stupid cow?
