The hypothetical physics of heat, energy, and work operating in reverse temporal direction. In retrothermodynamics, heat would flow spontaneously from cold objects to hot ones, friction would accelerate objects instead of slowing them down, and engines would run by absorbing exhaust fumes and fuel while outputting work and air. It's what you'd get if you took a video of normal thermodynamic processes and played it backward—a universe where every energy transaction is perfectly reversed, and the arrow of thermal time points the other way.
Retrothermodynamics (Physics) Example: "The movie scene where a character's breath unfreezes and returns to their mouth is a charming moment of cinematic retrothermodynamics."

weekend reporter

1.) The lone reporter in the ghost town of a newsroom after the five-day reporters head out to live normal lives. This reporter is responsible for anything that happens on Saturday and Sunday. Most of the time this means sending the reporter to a stupid event usually involving cute animals and children. This likelihood heightens during the summer months when festivals are rampant.

2.) Someone who has no life and has self image and self esteem problems. Probably has never touched a girl in their entire life.

3.) A sad, sad excuse for a person and a reporter.
4.) Awesome.
Reporter 1: Hey man, I'm going do something awesome this weekend. Do you wanna come with?

Weekend Reporter: I can't, if I don't come in the bunnies won't make page 5.

Trip Report

Trip Reporting is a silly pastime typed up by fat, un-original, inane people that travel a lot but don't actually do anything interesting. They then write about what they did (the irony) which is nothing... then post photos which only consist of food on the plane, at the hotel and at airport lounges. Some may post shots of the menus for good measure.

Very intrepid.

They are also tight-arsed as well since they seem to only want to use miles they accumulate while flying very short distances more frequently in order to pay for their long haul trips rather than hard earned money. You'd think by doing this they would actually have some cash to spend on doing something more meaningful and worthwhile ie. sightseeing, hiking, cultures etc...
This isn't the case.

Trip reports really should be called Service/Food reports.
Thread starter: Cathay Pacific Premium Economy JFK-HKG RT!!! and my Business Class trip on Air France A380 LAX-CDG Trip Reports!!!
"Please find attached my many professional photos of food!!!!!! oh and the seat I sat in"

Reader: Cool story bro you went on a plane, looked at a menu and ate food... but what did you do on your trip?

Thread starter: Oh I flew on a plane and ate food, then did the same at the hotel! Much fun, so cool, wow.

Reader: *facepalm*
