Google Mc Fuck 

Privileged techo nerds that think that all modern problems can be solved through money, research, and high I.Q.s.
Nerds that think Science and Math is more important than Wisdom and Common Sense.

These damn Google Mc Fucks have taken over the Bay Area like a bad Revenge of the Nerds movie.
