Whats the definition for them anyway?

hedging expressions is softening speech, for example saying "i dont like movie but." the 'but' is hedging as it's decreasing the force of the sentence, discourse particles are words 'like, so' that dont actually contribute to the actual content of what you are saying just there to serve a purpose which could just be because its spontaneous speech, or express nervousness, or even used to hedge.

Hedging expressions are discourse particles which make the sentence it is used in, appear more
'friendly' or 'casual' or even more polite: "Do you want to go to the mall?" as opposed to "Do you, like, want to go to the mall?"
The latter sounds much more friendly and less-imposing due to the hedging expression: 'Like'
A discourse particle does not contribute to the content and function (usually) of the discourse, but
it serves various purposes such as to mislead, to 'buy time' in order to think of what to say
"In biology, cultural evolution is... um.. a theory that explains how culture changes over a span of like... generations.. uh..." etc  -  the 'um' and 'uh' fills in for the space of what-would-be-silence and maintains the speaker's turn in speaking, as well as giving the speaker more time to think of what to say next
