Tasha,
I think you were wanting to know what "KLONK" meant. If you are referring to it's use in the Missy Elliot track the word is "Krunk"
Krunk
Originally derived from the two words: "crazy drunk".
Severe intoxication or getting drunk; a very fun or enjoyable time; also used to describe something cool, hip, or fashionable;
Yo, I'm on my 8th shot... this party is krunk!
Last night was krunk...
Homegirl's outfit is krunk!
Hope that helps.
