(Not to be confused with the common refrence drug pusher from Mean Girls.)
A pusher is a person who is afraid of change, yet has a once and a lifetime opportunity to change; but instead, the person just pushes the opportunity away in fear of the outcome.
A pusher is usually listed under these types of people: depressed, emo, drug users, synthetic or plastic.
Someone that tries to force the people that say the word no to them to do something (such as wear a mask or get a vaccine), since they don't take the word no for an answer.
The bubbly girl was a shallow pusher that lived in her own little bubble where there were no consequences to trying to push people around.
