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"
