The term "omgwthigo" is an acronym that stands for "Oh my gosh what the heck is going on?!" normally used when the
person either truly is clueless on what is happening (usually wherever the other
person is communicationg from) or as an expression while in a confusing online conversation, mostly with more than two
people involved.
The longer version is more explicit, and self explanatory on what it is
"omfgwtfhifgo"
