When you take a big shit in a public restroom, and you forget to give other patrons a courtesy flush, and it stinks up the whole restroom. When you walk out of the stall, it is refered to as the walk of shame because all the other patrons are pissed at you for the stench they had to endure.
James walked out of stall after pinching that floater, but he soon saw himself doing the dreaded walk of shame.
to have a escort/hooker come to your hotel room after the hotel stops letting guest up the elevators on their own. You have to go down to the lobby and meet your "niece" and walk her past everyone in the lobby in the early morning to the elevators, hence the walk of shame. Mostly used in Las Vegas
I was so horny last night I resorted to calling a hooker but it was past 1am and the Bellagio only lets hotel guests up the elevators at this time. I had to go down to the lobby pick up the hooker and make the walk of shame back to the elevators.
When the only way to get McDonalds is to go through the drive through, but you don't have a car. Hence you have to queue up in line with the cars and just stand there waiting for your food.
Popularized in Australia, particularily Sunnybank where late night gamers are forced to take the walk of shame in order to get their McDonalds fix.
