BF

British Fuck. This expression is used in areas (within the UK or abroad) where British people are present and you want to talk about them (and their annoying habits, physical appearance, etc) without them knowing and without appearing rude.

Look at that table full of disgusting BFs. Are they going to eat all of those sausages?
