Shut Up It's A Good Idea, OK?
When someone kinda rolls you, but you still like your idea.
For instance, if you wrote a song with the first lyric being "and", and someone said "why would you start a song with "and"?" you'd say SUIAGIOK
"Shut up it's a good idea OK".
When someone comes up with a bad idea, and you point out the badness of it, they might come out with something silly such as "SUIAGIOK", as opposed to actually admitting they were wrong and trying again.
Anyone with half a brain would use the tried and true STFU, as opposed to attempting to defend their idea with the pitiful and needlessly long SUIAGIOK. Not to mention the fact that SUIAGIOK is not very well known and thus will just leave the other person stunned.
