please, help me find this murph moment: GLEAVE [NS]

my friend and I both have this vivid recollection of a murph story where he explains that he/his family? inexplicably made up the word 'gleave' (gleeve?) as another word for throwing up, and when he was young, he went up to his aunt and said 'i'm going to gleave!' and then puked. I'm not 100% sure of the details but I do know the word is GLEAVE because it instantly entered me and my buddy's vocabulary. we have searched far and wide but still no hint thus far as to where it came from! please will somebody help us! thank you most kindly...
