increasingly verbose meme

A type of multi-frame image in which a lackluster or overused meme is replicated with poorer graphical fidelity but increased verbosity successive times to the point where it is difficult to understand the meme without the original context. Also called 'meme corruption' or 'progressively verbose meme'.

Captions of an increasingly verbose meme:

Frame 1: It's high noon

Frame 2: The time is 12pm.

Frame 3: The grandfather clock currently displays a reading of twelve o'clock post meridian.

Frame 4: It has become increasingly apparent to me that due to the rotation of Earth relative to the Sun, the current "time" as defined by Ancient Egyptians via the decan system is denoted by the numerical value "twelve" of the clock, signalling that the Sun is at the highest point in the sky.

inbreeding 

The breeding of people/ animals/ plants that are closely related to each other (first cousins or even closer), thus keeping the genepool weak and leaving them vulnerable to various health problems, mentally and emotionally as well as physically.

Purebred dogs and royalty are notorious for inbreeding; to keep the line "pure" then they are only allowed to procreate with their "own kind", even when offspring are stupid, sickly, deranged, ugly or any number of things.

Carlos II of Spain was the end result of the Spanish Hapsburgs; his parents were uncle and niece and both were highly inbred. Carlos was deformed, retarded, delicate, and had an extended infancy and premature senility. He was married twice, but he was impotent and sex was beyond his abilities.

Plants can be inbred, too; bananas of today are very different from those of three generations ago and often lack the genetic diversity which would keep them healthy.

Inbreeding depression 

1.) The lowered overall fitness of a population due to reproduction between closely related individuals, thereby lowering heterozygosity in the population and allowing deleterious alleles to be expressed.

2.) The crushing guilt that follows fucking your sister.

Inbreeding depression is a serious risk in small populations.

uncreeping 

The act or actions involving going through old content on someones' myspace/facebook/etc. (such as an ex, boss, etc.) to delete old messages, comments, and other things that you know longer want public due to withstanding situations.

After I broke up with my girlfriend, I had some 'uncreeping' to do to all my mushy comments from herspace.
