Diethyl ether 

Diethyl ether is a solvent that is useful for grignard reactions. It's also an anesthetic. Diethyl ether is highly flammable (even electrical outlets and too high temperatures can ignite it. Diethyl ether must be stored with butylated hydroxytoluene to avoid peroxide products which are explosive. Diethyl ether is also sometimes used for extractions, but other solvents like ethyl chloride, chloroform, toluene, hexane, and dichloromethane are generally preferred. Diethyl ether is synthesized by reacting ethanol with sulfuric acid. This reaction must be carried out at temperatures lower than 150 °C in order to ensure that an elimination product (ethylene) is not a product of the reaction. At higher temperatures, ethanol will dehydrate to form ethylene. The reaction to make diethyl ether is reversible, so eventually an equilibrium between reactants and products is achieved. Getting a good yield of ether requires that ether be distilled out of the reaction mixture before it reverts to ethanol.

I reacted ethyl magnesium chloride in diethyl ether with acetone, then reacted it with hydrochloric acid, and got 2-methyl-2-butanol.

diethyl ether 

(C2H5)2 O or C4H10 O

A colourless, volatile, highly flammable, sweet-smelling liquid hydrocarbon belonging to the ether group. Its primary use is as solvent, starting fluid for engines, cleaner alternative fuel and of course medicinal anaesthetic. Diethyl ether is one of most commonly used ether compound.
Diethyl ether is also isomer of butanol (C4H9OH).

girl grip 

The ability girls and women have developed to hold several items at once in one hand. The skill has been developed due to the lack of pockets in women's clothing.
I thought she'd need multiple trips to carry her phone, keys, wallet, and Starbucks to her car since she needed the other hand to open the door, but she used her impressive girl grip to carry everything in one hand.

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."
