hacking
Hacking is when you sneak into a computer and mess around with its files, but you don’t go full psycho and try to destroy it. Most of the time, hackers are the good guys trying to catch the bad ones.
I hacked my teacher’s computer and changed his grade to an A. He still gave me a B.
I snuck into the school system and changed all the math tests to say ‘easy’.
I hacked the cafeteria and made the lunch menu say ‘mystery meat’.
