I visited this site a few months ago and it was similar to what you were expecting with entries likeOriginally Posted by XanBcoo
"Today I purchased an apple as part of my lunch. The apple had some bruises on it. I ate it anyway. MLIA " or
"Today, I made a joke about blondes. There was a blonde there. No one cared. MLIA"
It was pretty much just a parody of fmylife.com and rather amusing for a while, and now the majority of the entries are exaggerated or fake stories that are, like you said, anything but average.
On the subject of these type of sites, my favorite one is probably notalwaysright.com, very entertaining to read through if you have the time.
