== "Hebrew and Yiddish influences" == 

 There's no evidence that Hebrew has influenced the infixation of fucking etc. (and the process doesn't exist in Yiddish). Note that Lighter's Hist. Dict. of Am. Slang attests infixation of bloody in Brit. Eng. from WWI. There's also no Hebrew model for reduplications like topless-shmopless, and in any case, Hebrew has had virtually no direct influence on colloquial spoken English. This is a pure yiddishism.
