What is No Bull?
1.
Originally used as the tagline for a very cheap beef-flavoured noodle product which was safe for vegetarians. The phrase is now used to describe that there is no meat in a product.
The sister phrase "Ain't no chicken" originates from the tagline of the chicken flavoured noodles. And is used in the same way but only when the product is chicken flavoured.
Eg.1
Man: Would you like some of my beef-flavoured noodles?
Vegi: Is it safe for vegitarians?
Man: No Bull!
Eg.2
Man: Would you like some chicken flavoured crisps?
Vegi: Is it safe for vegitarians?
Man: Ain't no chicken!
