baby hook
A woman (occasionally a man) who isn't a hooker or escort but rather is a sugarbaby with multiple sugardaddy or sponsor that are giving her an allowance for sex. These women delude themselves in to thinking they're not being paid for sex though the men are traditionally old enough to be their fathers or even grand-fathers in certain instances. Once they get a taste of the ease of money, many move from having 1 sugardaddy to multiple, blurring the lines of prostitution thus "baby hookers" or a "baby hook".
Tony: I met a new girl named Crystal last week and we're in an arrangement.
David: Me too! I though I was the only sugardaddy she had, she must be a baby hook
