Liquid Gold Digger is:
'A friend or significant other who is only with you for the Velveeta. They’re always asking for Velveeta or trying to charm you into making them a delicious Velveeta recipe'
I love the Pot Luck dinner commercial where the tool is trying to hit on Bernice for her Mac n' Cheese.
Certain times of the month, I become one of these 'Gold Diggers'
