When a man realizes or finds out during mid sex that woman he is having sex with is not really a woman and in fact is a man who had a sex change operation. Like that one episode of South Park.
"Dude did you hear Joey got Mr.Garrisoned by some "chick" at the club?! He found out halfway during sex that "she" was a he!"

Garrison Forest School is a college prep school located in Owings Mills Maryland. The definition of a Garrison girl is non-excistant. The diversity in the school makes it impossible to label any one stereotype. The closest attapmt so far is this however: a Garrison girl is one that is studious, athletic, and an all round curtious person.
Garrison Forest School boasts excellent academics in all fields. With brilliant English, Language, Mathmatics, Science, Art, Computer, and History departments, the school is well prepared to point these girls in the right direction for success. Garrison keeps the girls occupied on the weekend with the always entertaining weekend activities provided by the teachers, and the students. Most of the inspiration for these activities come the many clubs that call Garrison their home. So with your new found knowledge of the Garrison Forest School, i hope you use it well, and have a nice day. Thank you.

"The Forest" as it is called is home to many many many many many many, bitches, these girls are very aggressive when choosing their mates, and don't stop until they achieve what the label to be success. Many are very pretty, but don't be fooled there are many ugly garrison girls, many are also drunks, and at the same time have 4.0 GPA's. Don't ever approach a moderately attractive Garrison Girl...she will rip your fucking neck off, with her annoyingness.

However there always are excpeptions, and there are normal, non-aggressive, pretty, and smart Garrison Girls. But beware, even they have problems.
