Stop chatting jargon!
Jargon, the use of specialist words and expressions by a professional group is difficult for others to understand.
Would talking about Laver's phatic tokens in this sort of context be necessary?
Using specialist language in your occupation is necessary as there are people around you who understand the language and the language genuinely tends to be specific to the context. However it immediately becomes unnecessary in everyday situations, using jargon in everyday situations can be seen as the most pretentious thing to do, I mean seriously who in their right mind would like to talk about the synthetic personalisation used in a restaurants menu?
Famous linguist Howard Giles' theory argued that when people interact they adjust their speech, their vocal patterns and their gestures to accommodate others this is known as converging your language and diverging your language being the opposite of converging your language. Giles also said that people who converge can end up over accommodating it and be seen as condescending.
Bringing specialist language into everyday conversation can make simple conversation difficult for people who are not of the same job field as you, although all the specialist terms used for you may seem understandable other people may find it difficult to understand making it much harder for you to get your point across.
