''Zazz it all!'' -a Common way to use the Word.
the Word Zazz is a common word/slang/phrase that gets used in the year 2035 presented by the Back to the Future IDW Comics. the meaning of the word itself is never explained of fully contextualized in the comics, it is mostly used as some sort of exclamation or even a verb (ej. I zazz, you zazz, we zazz etc.) we first find out the word in Back to the Future Issue 9 Continuum Conundrum, part 4 on page 6 where a Roller Derbyist says ''Zazz that?'', a variation of the phrase ''What's that?'' but with Zazz replacing What for some reason. it can be also seen on Issue 10 Continuum Conundrum part 5 where a civilian exclaims ''Zazz it!'' when he sees Doc's about to crash on him, aswell as a bit later when Aiden says ''For Neos and Civvies' sake, Zazz it all!'' while Recording his Cast about A Match made in space getting a Second Reboot.
an example of a real-life word with similar use to ''Zazz'' could be the Spanish Word used in Center America on the Country Costa rica, where people usually say ''Pura Vida'', this word can be used as a salute, a goodbye, a state of emotion, an exclamation etc. just like how People in 2035 use ''Zazz'' as we can see.
