Words I Would Say if I Were British

I'm a little bit tired of my normal American English phrases like "Awesome" and "Totally Freaking Awesome". And I sometimes wish I could toss in a few select British phrases to spice things up a bit. But I don't for two reasons. First, there's a strong possibility that I wouldn't be understood because Americans are widely recognized as morons, and Second, if I were understood it would be by people who would think I was a totally lame poseur and I'd be shunned from decent society. So I refrain. But oh, if I could possibly get away with it, I would.

These would be my word seasoning of choice:

• Brilliant or Brill - "Penny, these new highlighter pens are simply brill!"
  
• Prat - "That prat Roger called me again last night."
  
• Git - "What an insufferable git!"
  
• Sod off - "Sod off, Aaron, I'm not buying your appetizers."
  
• Knackered - "I worked like a demon today and I'm completely knackered."
  
• Veg - "What lovely Fruit & Veg!"
• "Fill in the blank" for England - "You'd think Lucy was Shagging for England!"
• Naff - "Britney Spears is so naff."
  
• Love - "You about done with the copier, love?"
  
• Do - "Are you going to Harry's Birthday Do?"
• Spiffing - "Don't you look spiffing?"
  
• Corking/Corker - "Poppy's new dog is a little corker."
  
• Cock it up - "As usual, Ed cocked it up."
  
• Take Away - "Care for a curry take away?"
  
• Blimey - "Blimey it's cold in here."
  
• Did do - "Well I guess you did do."
  
• Pissed - "Roger, is that you? Are you pissed again?"
  
• Bollocks - "Bollocks to him! ... Yeah, bollocks to him!"

Wouldn't it be brill .... I mean awesome?
