Post-Haste Post 

The act of posting an image or text too quickly onto social media before it has been properly edited, resulting in errors such as misspellings, poor grammar, or improper abbreviations which can lead to feelings of remorse or regret in the person making the post.

Mary regretted her Post-Haste Post to Facebook of her husband Morty pictured at their 20th anniversary party with him holding a can of Coke in one hand and a piece of cake in the other which she inadvertently captioned, "Everything goes better with Cock"!

The Post-Haste

(n.) a legendary venue located in San Francisco's Lower Pacific Heights district known widely among San Franciscan's as the contemporary go-to spot for wildly exotic and scintillating social gatherings.

The Post-Haste has hosted crowd-pleasing events such as the South of the Border Occupation Celebration, Roll up a Phatty - Sushi, Wrath of the Renaissance, Rubies and Ruphies, Live 3 or Die, and 80's for Adam.

"Hey are you going to prom at The Post-Haste this Saturday?"

"Oh hell ya, I'm going to roll up out the cut around 11 and do the Macarena until my eyes bleed."

The gentlemen-like way of requesting pictures. More so than "PICS NAO" is anyway.

Person 1: "She then took her panties off and kissed my tophat and monocle!"
Person 2: "Attractive British woman you say?! Photographic evidence posthaste!"

posthaste 

Despite low lighting and doey-eyed (sic) coruscation dampened by same, the bright spirit that clamors through with a swiftness known only to spawning salmon on a path of destiny known only from inspiration, one making their way to the fur coat locations of a much talked about button only moments after sharing pleasantries of deeply fostered expectations, tempered by mutual self-doubt.

In other, "Where's Shorty?" and "May I?'. Life can wait.

The seemingly fleeting period of time between meeting for the first time and some genital awareness that follows a very, very quick unzip and mutual consent and insertion between loving meat lips that could only be described as posthaste..
