Learn a new phrase in a different language #2: Actions speak louder than words

What I’m liking about this challenge is the fact it’s full of surprises. I did not think I’d learn this phrase. A randomer taught me this on a night out last weekend, in a bar 15 seconds away from my flat.

Now I'm going to be polite and just say the acronym of this phrase….BS. Its either in sign language or Makaton. And because I learnt it from a stranger, who said his mum taught special needs so would know, I'm still not entirely convinced. But it is a phrase in a different language, so on to the next one wherever it comes from!

And why the sunglasses in the picture….why not?!
