No, I'm an English teacher and a student taught me this phrase a few years ago. I had never heard of it before. I think often local areas have their own phrases for this. I would use the phrase 'third wheel' but I've met a lot of people who have never heard of this phrase...

Hi, a "gooseberry" is an old fashioned slang term for a person who will tag along with a couple or a few couples, but they themselves are single. Usually it is an ugly friend or acquaintance who you can't bear to leave out as he/she will feel awful. Example: XXX is such a gooseberry, he always tags along with me and my boyfriend. to the cinema We don't use this term in Australia, instead we call such a person a "tag along".
