A shity school in the beautiful city of Frederick, MD which is the hot spot of rednecks also known as ‘Fredneck’ by many locals in the area. The school BCMS or “Ballenger Creek Middle School” is one of many middle schools in the middle class area of Frederick county others being “Crestwood Middle School,” “Westfredrick Middle School” And “Middletown Middle School.” While being the 2nd least ‘Ghetto’ school in the bunch behind “Middletown Middle School” it’s quite old almost as old as some of your parents (it’s almost 34 years old). Very little has changed since any of my siblings have attended this school including the teachers which leads right into my next topic the ‘Teachers’ if you will. Most of them are really nice to you but some of them are straight up ignorant in every way, shape, and form they’ll treat some students like absolute trash and some of them will be racist against some students but that’s pretty rare. The students here in my personal experience are mostly relaxed and don’t start beef but on the other hand there are some who are going to hate you and try to start beef but not everyone’s going to like you right? Overall this school in my 3 years is a 3.8/5 at most.

The word 'flag' as pronounced by people with thick Belfast accents. The term is a perfect encapsulation of the disproportionate and overblown reaction to the removal of the Union Jack (as in 'de fleg') from above City Hall in Belfast. Where previously it had flown for 365 days per year, it is now flown on 17 designated days of the year - in line with many other British cities.

The event caused a portion of the Protestant community ('fleggers') to make international pricks of themselves as they proceeded to wreck the fucking place, claiming it was another erosion of a 'British' identity they perceive to have been under attack since the horrifying spectre of equality reared its head in Northern Ireland.

The word 'fleg' - and indeed 'fleggers' - fittingly describes a section of humanity unconcerned with knowledge, reality or the vagaries of the English language. Like America's tea-baggers they are ruled by instinct, fear and paranoia with a side dish of rampant bigotry and startling ignorance of the world around them.
"Wat de fuck like! The taigs got de fleg took down! Let's wreck de fuckin place! No surrender!"

"De fleg has been took down! Before ye know it there'll be a united Ireland! Attack Short Strand! God Save The Queen!"
