N-N-N-N 

An extremely boring and dumb rhyme scheme used in songs in which each line ends with the n-word.

Notice the N-N-N-N

This is Britney Spears when she was bald (N)igga
Punking niggas way before there was Punk'd (N)igga (true)
Smoking Ashton Kush, so I calm down, (N)igga

K.D.Y.K.N.Y.O.K.K.M.H.N.H.N.N 

An abbreviation of a line from the intro to an anime called “your lie in April” typical said as a sign of affection and love.

It stands for

Kimi da yo kimi nanda yo. Oshiete kureta Kurayami mo hikaru nara Hoshizora ni naru

And translates to
It was you, it was you! The one who made me realize; if we can make even the darkness shine, it will become a starry sky.

Me: hey darling. K.D.Y.K.N.Y.O.K.K.M.H.N.H.N.N
S/O: I love you too you goof.

got dat G.U.N.N. $

The act of getting your YouTube video tweeted out by a media outlet/celebrity (such as James Gunn) which then causes a chain reaction of increased popularity. The increased popularity of the video results in increased advertisement revenue for the creator, hence the dollar sign. However, the root of the term comes as a play-on-words for the Fergie song "M.I.L.F. $".

After recreating the Guardians of the Galaxy 2 trailer by himself and getting it tweeted out by James Gunn, Hux got dat G.U.N.N. $.

r-u-n-n-o-f-t 

The condition of having left or abandoned someone or someplace, often abruptly, under difficult or unpleasant circumstances, and with the implication of not intending to come back. Colloquial misspelling of "ran off." The term is derived from the movie O Brother, Where Art Thou, in which an rather unlearned character wishes to convey to other characters that his wife left him but does not wish to say so aloud in front of his son.

D.E.N.N.I.S System 

The D.E.N.N.I.S. system refers to a fool proof system enabling men to obtain a woman's undying love, accompanied by life love devotion (if the man so desires). The D.E.N.N.I.S. system was made popular by Dennis Reynolds, a fictional character from Its Always Sunny In Philadelphia. The system, although original in name, is similar to "The Effect," which also goes by the separate name "DJGorbeism," popularized by D.J.G. When one engages in "the effect" they are "IN EFFECT."

D- Demonstrate Value
E- Engage Physically
N- Nurture Dependence
N- Neglect Emotionally
I- Inspire Hope
S- Separate Entirely

The way to win any girl's heart.

Example of the D.E.N.N.I.S System/In Effect

Kalie, "Hey this is some good pizza."
Dennis, "You're the one that is good."
