The shower one must take after a horrific experience.
Failed, yet valiant, attempt at trying to make it home before shitting yourself; Horrible break-up; Rick-Rolled; Watching 2Girls1Cup; Etcetera, etcetera
John: " I didn't make it home last night...it was horrible man, I had shit everywhere."
Steve: "Looks like someone had to take the Shower of Shame!"
A shower taken the day after a brutal night of debauchery and drunken hook-ups. It may involve crying, and thorough regret but is always satisfying and cleanses the body and mind of un-brushed teeth and octopus hands.
It is usually scalding hot as a self punishment.
After a night of drinking and making out with dirty Steve I had to have a shower of shame...it was the only way.
