It’s informal but I wouldn’t say it’s vulgar.

Thanks. Balls in English is slang for testicles, which apparently this is not.

To clear up any doubt the french equivalent for testicles is:

boules, couilles, testicules (Familier, Vulgaire)

“Balles” was a very familiar word for “franc”, the old French currency that was replaced by the Euro in 2001.

You can think of it as “bucks” in the US and “quids” in the UK.
