freving is the next level of overthinking, it's used when "overthinking" is not strongenough to define you
A:hey bro, you had a good night ?
B:nah i couldn't stop thinking about ranodm stuff.
A:oh yeah, overthinking.
B:it's not overthinking anymore it's freving.
What you call someone whos not your friEND (because even friEND has an end to it) but a person that will be there for you forever (because forever doesnt end in END). A person that is like your sister/brother, not someone that will stop being there for you when your out of high school or college, but someone who will continue to be there for you forever.
