Well, Canada == Canuckistan. The -stan suffix is not so much about what territory the Soviets occupied, as what countries in the world still desperately cling to the remnants of communism. So we could start calling the United Kingdom UKistan (pronounced Yuk-i-stan or Yuk-ee-stan) and now that I've just said it out loud, I think it's really apt, succinctly capturing the UK's yucky essence, as well as its communist essence.
Huh. And since "Pakistanis" refers to people from Pakistan, that would mean "Yuckis" would be the term to use for people from Yuckistan, I think.

Awesome.
OK, I'm doing that now. UK == Yuckistan.
