submachine gun 

A class of firearm that is intented for fully automatic firing and chambers pistol ammunitions. In some sense it is basically a pistol with full auto capability.

It is generally used in close combat where accuracy is less important than rate of fire. The usage of pistol ammunitions means lower recoil than conventional rifles, thus enabling it to be fired at high rate, but it also means it has less stopping power and a shorter effective range.

(note: civilian SMGs are often converted that so they are only capable of semi-auto fire.)

Do not confuse it with assault rifle. An assault rifle is technically a cross between a conventional rifle and a SMG.
HK MP5 is a German SMG.

Uzi is commonly portrayed in movies.

The M1 Thompson, or "Tommy gun" is a submachine gun used during the Second World War.

submachine gun 

A firearm larger than a pistol, without the range or barrel length of a rifle, or the speed of a true machine gun.

Submachine guns are basically firearms that can be fired in single, burst, or automatic fire with equal ease over short to medium ranges, after which point they become less effective due to inaccuracy.

Submachine guns can actually be rather large, like an MP5SD or FN P90, or small, like a Mac-10. Having akimbo SMGs is becoming amazingly popular in action moves and video games. (though in realistic games and real-life, are not reccomended due to heavy recoil and inaccuracy)
I turned the corner and was immediately pelted with lead. The guy had a submachine gun.

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."

Hair spider

A tight, tangled knot of loose hair and lint that forms inside clothing during the clothes dryer cycle. It typically hides inside garments, causing an annoying lump or a phantom tickling sensation against the skin until it is found or falls out onto the floor during folding.
