K: H is a gremlin
Gremlin by Ace the simp March 7, 2023
Gremlin by YaBoi93 January 29, 2021
Analagous to their malevolent movie counterparts, the modern-day Gremlin is most often found on weekends in between the hours of 1800 and 0400. When in its passive form, the Gremlin is most often a well-intentioned and meaningful contributor to society. However, when provoked (usually by means of an ex-girlfriend or obnoxious fool at the bar), the Gremlin first becomes forlorn and introspective, then mischevious, and in some cases violent.

If you encounter a fully manifested Gremlin, you are advised to stay clear (especially when the Gremlin is in a doorway). If you feel the need to intervene, it has been said a trip to Burger King can passify the creature.

The Gremlin will return to its natural state by morning, usually feeling embarassed and apologetic.
"Ryan and Pat went so Gremlin last night. They painted Blaine's car!"

"If you don't call me back I am going to go Gremlin."

The gremlin is a furry critter that will use her petit stature and nubile appearance to gain the trust of others. Upon making the mistake of trusting a gremlin, she will then lurk in dark corners and attack at any given moment. This evil hobbit will engage in acts of deceit and general tomfoolery as a means of social interaction. Characteristics of the gremlin will include:
-Rage blackouts
-Violent attacks from behind, especially on the knees
-Full speed bodychecks
-Stealing food from gardens
-The belief that she is average height, when she is in fact, gremlin height
-The use of such phrases as "frig-a-mug" and "go S a D"

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
