A peculiar phenomenon with millennials who all think every other person in the world is an utter imbecile so they start every explanation of anything, even the most simple concept that all previous young adults of previous generations grasped easily before finishing primary/elementary
school (e.g. saying 'Basically if you add 2 to 2, you
will get four. Basically'"
This immediately makes anyone (usually older but there is hope too for the children younger than millennials) with half a
brain think the speaker is a patronising moron and stop listening to said
idiot who assumes and is insinuating that everyone else on the planet is an
idiot but only makes him or herself an
idiot in the process by saying "basically" all the time.
"Basically" should only be used by people who actually have studied something to expert level e.g. advanced physics, mathematics, language, history.
