fallergies 

Various irritants that descend upon humans and plague them during the fall season. A combination of "fall" and "allergies."

I'm expecting the worst when the 1st round of fallergies hits me.

Fallerize

Fallerize The art of making ones clothing look as though it has turned the corner from Summer to the crisp days of Fall.

This word came about because a lot of people are always looking for ways to transition their wardrobe from summer to fall, so instead of always writing out we came up with a word for it. I'm sure it's been used before so I won't take credit for it but I was trying to describe making an outfit and blurted out the word fallerize. I looked it up and it was in fact used on the internet so I came here added it to the urban dictionary. I don't have "way with words" so if someone can polish it up and add some more to it that would be great.

She should fallerize that outfit by adding a brown jacket

Fallergieson 

Canadian military slang for allergy-related frustration. Often related to poor timing of sneezes, coughing, sniffles, and other allergy symptoms; for example during inspection, while observing the enemy, or while trying to hide from the MPs after they bust your coke dealer.

Morty is on the OP and sees the enemy, but he finds himself in a life-or-death struggle to suppress a sneeze so he doesn't alert the enemy. He is experience severe and visible fallergieson.
"Man I had some serious fallergiesons during the OC's inspection this morning."
