"Googar Juice" is uncommon slang for pomegranate juice - usually in a tetra pack container - that is used the East-Midlands of England.

The phrase originated when popular rapper stormzy visted a Tescos supermarket in the Leicestershire area and couldn't rhyme a word with booger so settled on "googar". He later explained he was referring to pomegranate juice.

Boy 1: Shut up you don't even know what a googar is
