While its original meanings has been distorted from its ancient Chinese origins, it is popular in Southeast Asia is a semi-curse word. Its rise to popular culture has been spearheaded by Southeast Asian movie "The Maid", where the main character's primary name is called "Ah Soon", who plays a retarded teenager.
Bob: Don't be a Soon.
Tom: Lets hang out at the mall.
Bob: Why are you being such a Soon?
Tom: I wish I could fly.
Bob: Don't Soon.
Bob: That moron Tom told me he could fly. What a Soon.
Tim: Wow, that's really quite Soon.
Otherwise there is another soon. the Blizzard "soon" which can be a very LONG time 6-24 months actually.
Yeah right, more like in 2005
The origin of this phrase is in an under-appreciated lolcat, where an evil-looking cat is watching a chihuahua, with the only caption being SOON.
When pronounced, it helps to add suspense and drama by saying "SOON." in a low voice employed by that movie advertising dude.
