you know when you hear/learn/observe something you've never done before and then you hear about it or see it again THE SAME DAY and think 'that's wierd?'
it's the perfect word for describing that bizarre situation.
1) i heard a word the other day i'd never heard of before and asked the meaning. then when i got home, some guy said it on the news! oidamucho
2) someone mentioned to me how many rubber bands there are in london if you look down at the pavement. now when i walk around i can't NOT see all the rubber bands and i wonder why i never noticed them before. that's oidamucho.
it's more than a coincidence. it's oidamucho.
