-unintentionally made you feel less intelligent than them because they were comfortable using words you didn't understand, only to cry foul when someone punched back. that's behavior that reveals a lack of self-awareness and deep insecurity.
I don't say this as an insult, but instead in the hopes that you'll learn from it and act differently going forward. you seem like you're a decent enough kid but you were way out of line here. sorry for being rude earlier.
