Callahan 

An elderly confused man, suffering from dementia. Reliving his glory days without realizing he is indeed much past his prime. Essentially any 80 year old who believes he is still capable of being a functioning member of society.

The orderlies at the Mohecan elderly home on fox news were quoted "These Callahans just don't realize how little they are capable of anymore. They're stuck in the past, believing they are still playing college football with their leather helmets."

Callahan 

A shithole in Northern Florida with racist and homophobic republicans, who drive pick up trucks and flip off people of color. The children at the high school are demon spawns and clearly grew up here, so they pick up racist traits, and have horrible taste in music food.

Aw you live in Callahan. (Jacksonville resident)

Unfortunately. (Me)
Callahan is a town in NE Florida

Callahan Theory 

The Callahan Theory is performed when a person completes all of his/her homework on the absolute last day of the semester. No homework is done through out the course until the last day. Then, he/she hands all of it in to the teacher all at once. To complete the theory, you must still achieve a 3.5 GPA.

Matt - "Hey Pat, have you done your homework tonight?"
Pat - "No, we're only two weeks into the course, I follow the Callahan Theory."
Matt - "What's that?"
Pat - "It's when I do all of my homework on the last day of the semester, and still get an A!"

Callahan Fl 

A mostly white hellhole in Northern Florida
It's crawling with racist and homophobic Republican hicks. Has a population of a little over 1,000, but has a fuckton of churches. Most boring place on earth. If you're a minority, old white people will give you looks of disgust and fear. Don't live here!

I almost got shot by a bible thumping hillbilly in Callahan Fl when he saw my Ridin' With Biden flag
