crasterful 

| CRAH-ster-full |

adjective
To be simultaneously crafty and masterful in an abundantly confident way.

(also: crastery, noun)
The act of being crasterful.

One is crasterful in an authentic way when one demonstrates the depth of one’s skills, knowledge, or experience. In this sense, the crasterful person is a true expert in his or her field and displays a justified level of assuredness.

One is crasterful in an inauthentic way when one fancies oneself knowledgeable but is actually full of shit. This is exemplified when one does not really know what one is talking about but arrogantly rambles on regardless.

Since being crasterful usually manifests itself in the form of explaining something in a very knowing, self-assured way, it can be difficult to discern precisely how knowledgeable the person actually is. While it can be prudent to attempt to determine the authenticity of one’s crastery, this is not always possible. Moreover, contrary to popular belief, crastery does not have inherently positive or negative connotations; rather, it is simply a descriptor that demonstrates someone is “in the zone,” even if that zone is incorrect.

Oftentimes crastery can be expressed nonverbally, usually by flashing a crasterful smile. This look simply says, “You should listen to me, because I know what I'm talking about.” The telltale signs of a crasterful smile are crooked smirks, raised eyebrows, and twinkling eyes. Slow nods are also common.

“I was really crasterful while writing this definition for Urban Dictionary.”

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!"

To take something small, that doesn't quite qualify as a theft. Probably from the Danish "skæv" or the Dutch "scheef", both of which are pronounced similarly, meaning "askew, or not quite right'. To change an item's ownership without permission, but only something small and of little worth.
"I skeefed an apple off the neighbor's tree." "I skeefed some chips outta your bag when you looked away." "Don't skeef my chair when I go to the bathroom."
