A bloke is a word used to describe a man or a guy. It's a way to refer to a male person in a friendly and informal way. Just like how you might say "hey kiddo" to a younger person or "hey friend" to someone you know, people might use the word bloke when talking about a guy they know. It's like a nickname for men! So, if someone says "I met this cool bloke at the pub last night", they mean they met a friendly and interesting guy. It's a word that is mostly used in Australia and the UK, but it can be used in other places too!
