When a close friend plays a prank on you, and scares you, one may reply “You little bugger”. The prank wasn’t
right but you’re giving kudos to the
person who did it as it was actually a good prank even though it was
wrong.
When a family members does something hilarious
“You’re a funny bugger”
When someone has a lot of courage to say something that most wouldn’t.
One would say “oh you’re a cheeky bugger”. Impressed by what they said but also knowing it was said in jest
When a
cup slip off the bench and smashes on the floor. “Oh bugger”
