haha Karolinke :) You assume the man you are gonna flirt with doesn't know english (as bendy says) and also that he knows nothing about American culture and humor. BAD.

Many of the people who you would find interesting and would want to flirt with, have been to america one way or another, or at least a foreign country, has seen many US tv shows ( and yes most of it is true what's in there, although some disagree about the CSI finding criminals so fast :P)

I think that most men when they are drunk are easy to flirt with, because they think you are talking to them in another language anyway and they just smile and nod -- thinking man i am getting lucky tonight :P

You will do fine, although woman's psychology would suggest that the flirting for the new boyfriend of your friend would commence only when she is ready to go to the farm with white horses and cowboys with perfect bodies.
