IMHO, truly indelible branding can be achieved by tapping into the core of one – or all – of four distinct socio-psychological motivators. Fear, lust, love or greed.

For example:

Fear: Use this brand or you will look fat/old/disrespectful/uncool/cheap/ignorant/evil/boring etc
Lust: Use this brand and others will look at you like they look at (insert hot model, car, house etc)
Love: Use this brand to show your love/fanaticism/adulation/desire etc
Greed: Use this brand to get more/save more/own more/be more etc

Take these motivators and (if and when by fluke or foresight you manage to penetrate and hook into them) you then relentlessly and mercilessly exploit them to engender a viral referral, recommendation or retribution effect that self-populates like an asexual pathogenic amoeba. Fed by those motivators, the brand amoeba morphs into a life of its own and will invariably give life to sub-amoeba brands, due as much to the pervasive presence of its parent as to the sycophantic demands of the consumers who have fed it.

Take your brand and thrust it deep into the gut of a socio-cultural psyche and watch your brand name grow like a virus.
