How to use workestercestercesshirshiktrasectersaire sauce?

My little brother gave it to me cause he saw people using it on YouTube he says. It has... a meh taste, not very good dipping sauce, maybe it would work well with marinades? Just wondering what it would be good with.

I usually cook South Asian food (Indian/Bangladeshi/Pakistani), so any suggestions as to how to use it in this cuisine would be greatly appreciated. But I don't mind trying other stuff too.
