Infamous phrase originated by Gianni (aka: Viscosity, Johnny Vicious, Versace, Johnny Ball Sack, Johnny Blaze, etc.) King of the one liners. The original use of this phrase was to not answer an invitation to go some place or do something. Example: You- “Yo I am having a bbq on Saturday, come by”  Viscosity- “yea, let me know.” You- “Oook.”. -- Then -- (the day before the gathering)  You-– “So tomorrow is the bbq, you gonna come by?”  Vicious- “yo whos gonna be there?” You- “yo I dunno u know the usual peeps, just come by and hang if you want” Viscosity- “yo let me know.” You- “I am letting you know now!”  … This catch phrase if used in excess can grow to extreme annoyance and lameness.  In the occasion of excessive use, a response phrase of “what do you want to know!”….  “Let Me Know” also “Lemme Kno” has transformed and expanded to many uses and applications.
