A. Common terminology used in such MMO RPG games as World of Warcraft, where a skilled player jokes about pwning a foe.
The term 'face roll' suggests that the person doing the 'face rolling' can beat their opponent by just 'rolling' their face along the keyboard, defeating their foe almost effortlessly.
B. "Face roll" can also be used a derogatory term, used when insulting another person's poor skills, or lack there of, when using their MMO RPG character.
The derogatory "face roll" term suggests the player used no skill what-so-ever and simply rolled their face along the keyboard.
A. Player: Wow, that guy is such a noob. I bet I could face roll him.
B. Player: Wtf was that dude? Did you just face roll that last boss or what? We wiped because of you asshole.
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!"
