'Flon' means 'full on' - hardcore, massive etc.
It can also be used as an adjunct in place of, for instance, man, bro, or blud. Man is so yesterday, flon.
Works best with the good alliteration of the flong-meister:
'I flon flashed my flong'
'She's flon flonging it today'
Other common expressions:
'Wo man, flon!'
'He's a flon wanker!'
