When you are drinking beer in colder temperatures l, or the beer itself is a certain temperature opposite of the climate where it isnt refreshing anymore and causes a jaw-clenching pain in the bottom-back of your cheeks upon beer-sip contact due to your overloading of barely. This pain is a visit from the the Barely Fairy whom reminds us all to keep beer refreshing and at a responsible temperature while reminding to space beer sips out in colder temperatures with hard liquor or non-barley foods. The Barely Fairy has a mom tattoo, bandana and bad stubble and floats like a genie but is still a mythical creature like the Tooth Fairy with very little physical evidence; just folklore. He does't grant wishes; just gives you a sharp cheek pain probably caused by his domestic-violence genie punch.
Brent: "*ow* chuggin beer stings on this windy cool day; I think I got visited by the Barley Fairy."
Jordan: "yoh man; switch to rum and take your damn shot, the Barley Fairy has spoken; the temperature of beer to mouth ratio is too unstable."
