Deltic 

(n) A diesel engine where the cylinder arrangement is in the form of an equilateral triangle operating from three crankshafts (one at each apex) geared together to form one output shaft. As the pistons are opposed the engine is a 2 stroke type. The 9 cyl and 18 cyl types were used in high powered military vehicles, high powered marine MTB's and high powered high speed British locomotives. The Deltics ran from London to Scotland on the east coast mainline from 1960 to 1981. Six Deltic locos are preserved.

The 10 o' clock from Kings Cross to Edinburgh was hauled by class 55 Deltic D9009 Alycidon.

Raspy deliciousness 

Originates from the beautiful voice of South Korean and DAY6 band leader; Park Sungjin.

His voice is gifted with the perfect balance between raspy and delicious and has therefore been titled as “raspy deliciousness” by many.

Someone: “have you heard this voice? I can’t even begin to explain this sensation my ears are experiencing right now!!”

An intellectual: “it’s... raspy deliciousness”
