1) A ratchet is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Though something of a misnomer, "ratchet" is also often used to refer to ratcheting socket wrenches, a common tool with a ratcheting handle.

2) A character in the Transformers franchise. (Seriously?)

An unknown or unspecified person. No one knows who he/she is, until you meet them.

A person, usually a teenage girl who is obsessed with the British boy band, One Direction. They often go on Tumblr for hours a day reposting .gifs about the band and stick true to them no matter what. They're super biased toward One Direction.

They will go after you if you insult their band, and thus you are labeled a "Directionator", a fan who’s just discovered the band. If you can’t name all the band members or spell their names correctly, you’re a Directionator. If you think that Louis really likes women who like carrots, or if you somehow think that Liam likes spoons, then you are a Directionator.

"Gangnam Style" is a K-pop single by the South Korean musician PSY (short for psycho). The song was released in July 2012 as the lead single of his sixth studio album PSY 6 (Six Rules), Part 1, and debuted at number one on South Korea's Gaon Chart. On December 21, 2012 it reached over a billion views. Today it has about 1.25 billion views.

It actually is about the "class" that is to be found in the wealthy Seoul neighborhood of Gangnam, whose residents are known to party a lot.

Although, most non-South Korean PSY fans take this to mean a silly horse dance.

Just plain lame

A dance that resembles the riding of a horse, duh. More closely related to Gangnam Style. It has been a popular meme worldwide since 2012.
