Origin: In world of warcraft, one could destroy gear and turn it into jewel shards. Which could be sold for alot of money. When someone's account got hacked, the hacker would "shard" all the gear and sell the shards. They would then send the gold to themselves, or a stranger as a last fuck you to the player. This was also done by chinese companies who sell game gold online for real money.
She left her character logged in, so I went onto her account to shard her gear. I noticed she had an epic staff, so I sharded that too.
The term comes from MMORPGs that include a profession that destroys one thing for another. In world of warcraft, enchanting needed an ethereal type of material to craft enchantments on armor and weapons. It was obtained by "disenchanting" other pieces of special armor. The better the armor, the better the material. Because the material came out as dust and crystal shards, people called the act "sharding."
Because "sharding" a piece of armor would destroy it and replace it with expensive crafting materials, it was always a given that if your account was hacked by a chinese Farmer, he would shard all of your epic gear and sell the shards for gold.
It was also common for other players to do the same against one ex boy/girlfriend. See Example 1.
It became so ubiquitous, that it was used in games ever since. See Example 2.
It is also used by gamers in real life. See example 3.
A portmanteau of the verbs "shit" and "fart," which describes the instance of accidentally shitting one's pants based on the assumption of farting prior to release.
A bit of technical information:
Despite one's intuition that the un-inflected form of the verb would be "shart," (borrowing the onset from "shit" and the rhyme of "fart") It's phonological realization, "shard," implies that the word entered the lexicon as "sharted."
Much in the same way the words "writer" and "rider" can not be distinguished from one another in speech with out a rich enough context (because they sound the same), "sharded" and "sharted" will also sound identical due to flapping. Hence, speakers of English chose "shard" as opposed to "shart" by means of back-formation. Selection of the phoneme /d/ over /t/ can likely be attributed to the feature {+voice} of the flapped consonant.
The end result of a wet fart where one will find residual turd-lets in their underwear. If not cleaned promptly, the likely outcome of a shard and impact to the underwear is called a skid-mark.
After that mean bean burrito from Filliberto's, I ripped a huge fart and when I finally got to the bathroom, low and behold I found a raisin sized shard nestled in my underwear and another one smashed in my ass hairs.
A piece of crystal meth, a psychedelicstimulant, named for the shard-like crystals. Has nothing to do with shitting in your pants while farting, that's shart.
