shit that didn't happen: ie, when people post stupid
stories on
the internet to make their
boring lives seem more interesting than they really are
example 1: from
fml: "Today, my boyfriend went down on me for the first time. He definitely killed the mood when, while down there, he started saying, "Nomnomnomnom."
FML"
this probably didn't actually happen, hence, stdh
example 2:
Person 1: "...my uncle works at
nintendo..."
Person 2: "stdh"
