'Dlib' (드립), also romanized as 'Drip', is Korean internet slang for careless jokes or remarks uttered spontaneously, typically at someone's expense. The term stems from 'ad lib' (애드리브), in the 'without restriction' sense, but somehow became shorthand for a 'gag' or 'joke'.

The term is derived from 'gaedlib' (개드립), short for 'dog-like ad libbing' (개같은 애드리브),¹⁾ which originally described 'lame jokes from variety show entertainers' on DC Inside. As the term spread, the definition of 'gaedlib' (개드립) shifted closer to 'gag' (개그) instead, flipping the connotations into a more positive one, then came all of the brand new comedic genres that would include 'dlib' (드립) as a suffix.

• Jiyeogdlib (지역드립) - From 'jiyeog' (지역, lit, 'region“). A joke that makes fun of an area or a region.
• Sekdlib (섹드립) - From 'sekseu' (섹스, lit. “sex”). A sexually suggestive joke, or an innuendo.

• Goindlib (고인드립) - From 'goin' (고인, lit. “deceased person”). A joke that makes fun of the dead.
• Paedlib (패드립) - From 'paeryun' (패륜, lit. “depraved”). A joke that makes fun of someone's parents, which was seen as 'depraved' due to the influence of Ruism on Korean society.

• The term is a bit fickle to translate since 'ad lib' isn't the best descriptor. One may argue that it's more closer to 'non sequitur', 'improv', or 'stand-up' instead, but that's not up to me.
  • Of course, a term like 'gaedlib' (개드립) could be translated literally as 'dog drip', thus dogdrip.net, but a young English speaker would probably think of 'a dog with drip' (a fashionable dog).
• The process of making a 'dlib' is called 'chida' (드립, lit. “hit”). This is where baseball analogies would come in, with 'tayul' (타율, lit. “batting average”) referring to the amount of jokes that land.

• Anonymity - Partially needed, as real-world comedians don't want to destroy their audience.
