‘Weirdo’ means 'strange person'. For example - 'Why are you singing at work? You're such a weirdo.' It comes from the adjective 'weird', which just means 'strange'. It's not clear where this word comes from, but it *might* be Australian. Australian English oftens puts 'o' or 'ie' at the end of a word. For example, 'muso' = 'musician' and 'barbie' = 'barbecue'. The international English word 'selfie' probably comes from Australian English too.
A: Oh my God! You weirdo! Are you really going to kiss that frog?
B: Sure. And I’m taking a selfie of it too. I love frogs.
Are you a weirdo???
Do you know any Japanese words that have become part of English?
