Who coined the "walk of shame?" Aren't there people out there who are proud of hooking up? I, myself know there have been times when I called my girlfriends to let them know about some guy I'd made out with and there was no shame talk in any part of our conversations.
Of course, I can see where the actual walking part is embarrassing. Walking out of some guy's dorm room, apartment, front door of his house--but aren't you still to happy from the making out to feel shameful? Think about it. Or does the bad stuff, the embarrassing stuff take precedence over the good? That's shameful; really, truly shameful.
