Armstrong's Law
Armstrong's Law describes the phenomenon observed when discussions between Americans and non Americans about a variety of topics, where it become apparent America is not the greatest at said topic, the likelihood of the American to arbitrarily bring up the US moon landings as a non sequitur increases dramatically. Mathematically, Armstrong's Law is defined as the probability of the moon landings being inserted into the debate (P(ml)) increasing exponentially as a function of time (t) of the discussion, once it becomes obvious that America is in fact inferior in regards to the subject being discussed Thus: P(ml) = exp^(t) Named for American astronaut Neil Alden Armstrong who became the first human to walk on the surface of the moon on July 21, 1969. Amstrong's Law is recognised by science and has been observed all over the internet in discussions ranging from the geo-political impact of American foreign policy, to tackling poverty, to whether cheese in a can is really cheese.

I don't visit Urban Dictionary alit so I only recently saw they offered merch. I immediately started looking up words for potential Christmas gifts. Found the ideal gift for my brother & ordered a shirt. It arrived very quickly and I love it. It's exactly as pictured on the site and being able to customize it with his name makes it perfect. I only hope he loves it as much as I do. Will definitely keep Urban Dictionary in mind when I need to find a great gift.
