The 'Say Hi, Bern' meme originates from a brief but memorable interaction between Senator Mitt Romney and Senator Bernie Sanders during the 2020 State of the Union address. As Romney walks past a seated and seemingly stoic Sanders, he cheerily calls out, 'Say hi, Bern!' to which Sanders offers a curt or non-responsive reaction. The clip went viral for its relatable portrayal of forced social politeness versus authentic grumpiness. It is widely used to illustrate situations where someone is trying to be overly friendly while the other person simply wants to be left alone or is focused on more serious matters, capturing the quintessential 'introvert vs. extrovert' energy.
