A day that can occur any day. It is the day you and your partner have sex.
"Hey, Steve! How many humping days have you done this month?"

"None I wanna be a fucking virgin forever!"

"You aren't no virgin! We did porn together on one humping day!"

Get a Hump day mug for your brother-in-law Trump.
Wednesday, or the hump of the week
The absolute BEST day of the week, the day of maximum hope that maybe, you might make it out of this week alive. A particularly good hump day can last you the rest of the week, and by Doomday morning (Monday) you survive by anticipating hump day. Nothing goes wrong on hump day

Most other days can be defined by hump day. Tuesday is the day before hump day. Thursday is one day after hump day. Except Friday is WOOOH!!! FREEDOM!!! Day, Saturday is Mostly Hungover day, and Sunday is PreDoom day.

Hump day has nothing to do with sex. Unless one wants it to. I like to declare the existence of hump day just to see people's faces. Usually being conservative and all
"Do you know what the best thing about Tuesdays are? Its the day before Hump Day!"
"What's hump day?"
"It's the hump of the week!!"

Get a Hump day mug for your barber Paul.
Wednesday, the middle of the week, implying that you have to get "over the hump" before you can anticipate the weekend. The term was not originally intended to carry a second, more risque meaning.
Damn, I wish every day could be hump day!
