A neologic portmanteau of the words thrifty and thirsty intended pejoratively to describe a person who is thirsty but too cheap or poor to purchase a beverage. Transitively extrapolated to denote a person who experiences a tremendous gravity towards free shit.
"I'm so thristy I've been taking my subway cup back for refills all week."

Person a: "Did you come to my wedding just for the open bar?"
Person b:"Naw. I'm not THAT thristy. I also figured there'd be at least a few miserably desperate girls here."
