It’s time to break down another not often used word to determine what it really does mean.
It’s roots are three: Phil-is-tine
Since here it’s capitalized Phil is a nickname for that uncool first name Philip
is is a form of the present tense to be in the indicative mood
tine is the purposefully misspelled abbreviation for teenager
So here is the interpretative meaning that would win any wager:
Phil is a typical moody teen who has an intense dislike for art, culture, and anything spiritual
Who thinks it’s cool to be an uncouth anti-intellectual
