Definition: To continuously stare at someone with intense animosity Grillin’ Origin: Came from the African-American lexicon, I first heard it in July of 2005 from my brother who went to Miami for the summer, so this word possibly came about in Florida. Could have been an extension of the version of grilling meaning to question intensely. For example “the cops grilled the suspect for hours to no avail.” There is a connection between being investigated and being watched and being stared at all intensely and all involve some form of animosity. And finally the loss of the ‘g’ is common to most new words in the urban lexicon, an almost predictable clipping of all –ing words.
