YOUR SUGGESTED WORD: "ELUCIDATE"
Eluci-date and nut mix.
My mafia uncle always told me: "eh-you-looseadate, you find a new one."
Sam couldn't find the mysterious girl he was supposed to take to the movies because she was an elucivdate.
You know why you should never lend your underwater sea creature friend your healthy snack? Because eel-lose-a-date.
Verdict: Elucidate. Highly difficult for wordplay.
