"Nice one. You just pulled a Brian."
For instance:
"That math test was a bitch!" - in front of the principal's office at your private high school
"This school is NOT the shit" - while passing the head of
administration at your private high school
"HEY REF! GET OFF YOUR KNEES YOU ARE BLOWING THE GAME" - yelled in a quiet gym during a
basketball game at your private high school...while sitting right behind a teacher
"Who the heck made up that rule? that is the DUMBEST thing I have ever heard in my life" - when the maker of the rule (part of
administration) is sitting right in front of you
