when responding quickly in texting, the texter might respond "K" instead of typing out ok or okay... but will accidentally hit the "J" key instead of "K"...
"j is the new k" is like when referring to fashion and trends... "pink is the new red" "grey is the new black" or when someone gets a new boyfriend, "dave is the new john"
