Trainwreck? HotChickPicsNow

[Doc7]

Urban dictionary isn't helping. What does this word mean? Clearly it has to do with pissing a girl off by sending her to these forums (any forums? is this internet-wide or is the phrase an original outta OOT?) after having sex with her or doing something else that she'd be angry for if it was posted online. I'm just looking for a simple easy definition rather than a general thought : )
