Super (as an adverb) 

A word which has replaced the longstanding, commonly used adverb "very". It has also replaced the use of stronger adjectives, but this would require being more well-read and that's simply not possible for most smartphone-addicted automata in 2020. This fad has been growing exponentially since around 2015.

Commonly used by anyone who is trying to sound trendy, but comes off sounding uneducated, cringeworthy and just plain embarrassing. It is the height of poor vocabulary.

Examples of super (as an adverb)

I'm super excited! (elated) I'm super tired! (exhausted) I'm super happy! (delighted) The guy was super slow! (sluggish) It was super boring! (monotonous) I'm super confused! (bewildered) The car was super fast! (rapid) My room is super small (tiny) The lunch was super expensive! (extortionate) The class was super interesting! (fascinating)
