The phenomenon of heightened human receptiveness to humour during the act of consuming water (or any drink). Supposedly first documented in the 1920s by British neurologist Samuel Alexander Kinnier Wilson, who noted the increased likelihood of choking and/or spillage owing to exposure to comedy stimuli while sipping/swigging/supping.

The effect is where you show up at Lindsey Wilson College and you see all these girls and when you see them you're like oh she is a 6 or a 7 on the rating scale 1 to 10. With the Lindsey Wilson Effect it adds the original number by 2 after being on campus for a month in the middle of fucken nowhere.
