흠좀무

"Heum-jom-moo" (sounds like "Hoom-jom-moo" or "Heum-jom-moo," with 'eu' as in 'book')

"Heumjommu" originated around 2007 in the DC Inside Japan Animation Gallery and spread rapidly. Although its popularity as a trending phrase waned after 2008, it has been consistently used in Enha-style wikis like Namuwiki, following its use in Rigveda Wiki. Its influence significantly decreased with the release of a Crayon Shin-chan movie featuring a future Shin-chan in 2010.

"Heumjommu" is an abbreviation of the Korean phrase "Heum, ige sariramyeon jom museopgunyo;" which translates to "Hmm, if this is true, it's a bit scary." It is primarily used to express a sense of surprise combined with a slight eeriness or fear regarding a fact or story. This meme originated from a "Crayon Shin-chan ending" clickbait post in the DC Inside Japan Animation Gallery. It evolved from a comment "Heumsajommu" (흠사좀무) posted by a user in the cartoon gallery at the time, which was then shortened to the current "Heumjommu." Initially, it was also used in StarCraft game broadcasts to disparagingly comment on an opponent's build order.

It was popular mainly among the younger generation who used internet communities like DC Inside in the late 2000s. Currently, it is primarily found among users of Enha-style wikis.

• "If that rumor is true, Heumjommu."
• When hearing the full story of an event and wanting to express "Hmm, if this is true, it's a bit scary," one can use "Heumjommu" as a shortened form.
• In the past, it was also mentioned on the show "Funny TV Roller Coaster" when introducing new slang, in the form of "Heumjommuhande?" (Is it Heumjommu?).

Since "Heumjommu" carries the conditional meaning of "Hmm, if this is true, it's a bit scary," it's best not to use it for clear, undeniable facts. Using it simply to mean "Hmm, it's a bit scary" deviates from its original context. Furthermore, as its lifespan as a trending phrase ended after 2008, it is rarely used in everyday conversation and tends to be confined to specific online environments like wikis. Attaching particles after the word, as in "Heumjommuhande?" on "Funny TV Roller Coaster," is an inappropriate usage because "Heumjommu" itself already carries the meaning of a complete sentence.
