Its whatever you want it to be...Thought it was 'jaw'... as in masculinity,
First day as a man, etc
Growing up to be disenchanted with the other men (ie politics).
I also thought it was a reference to Bowie's 1984
'Beware the savage jaw'
Which according to online lyrics are actually
'Savage lure'.
I guess I'm dumb and should read the lyrics more often.
