The blue Lego-esque block shown in stead of Adobe Flash content when visiting a website in Apple's Mobile Safari browser. It has come to symbolize one of the greatest criticisms leveled against an otherwise highly regarded mobile browser capable of rendering most web content true to form. The debate over Flash's omission has swelled up once again with the introduction of the iPad which also utilizes Mobile Safari sans Flash support, albeit on far more capable hardware. While Apple claims to provide the "entire internet in the palm of your hand" their detractors are quick to remind the world that the "entire internet" includes quite a bit of Flash.

That moment after you drink where you act stupider and say stupider things, and although you consciously know you're doing it because you're drunk, you do it anyways.

When the shade of your skin changes significantly between seasons enough that people can't pin down what ethnicity you might be.

When someone gives off hints of autism, but you and or your peers are unsure of whether or not they are truly mentally impaired.
