Превод - Каталонски-Английски - jo penso igual que aquest noi

If it's not referring to a kid, it's a quite informal speaking, so it should be "guy" instead of "boy"

Do you agree Isildur?

I think it could be both "boy" and "guy", but uUnfortunately the context is not enough to choice with accuracy:

I'll quote: (http://dcvb.iecat.net/)

1. Very young man, specially the one which has not still reached the puberty. Spanish: muchacho. [...] a) In oral conversations, "noi" can be used to refer somebody of your age or somebody you've known for a long time.

ilginiz için çok teşekkürler
