The occurrence of when you attempt to wipe a shart on a hot summer day and leave some behind, the humidity forms a new damp layer over the leftover skid mark, and with a unique blend of body heat and weather, it produces the most putrid and ungodly stench known to man.
Terry wreaked of Humid Skid, causing Rich to dry heave.
Dave forgot to shower, therefore bringing his foul smelling Humid Skid into bed with him, causing Patrica to awake and puke immediately.
Joe neglected to fully clean the shart mess off his leg resulting in a Humid Skid from the tacos that Leah made for him.
The humidex is a computed value combining the temperature and humidity into onenumber. It is used to describe how hot or humid weather feels to the average person.
The number is only significant over 30 degrees celcius.
Essentially, on a really hot day, when there's signicant humidity, it generally feels way hotter than the actual temperature.
Holy crap, the humidex just hit fucking 40!!! It's too fucking hot to exist today!
(for those who live south of the border of Canada and the USA, 40 degrees celcius is actually 104 degree fahrenheit)
