The term used between girls when describing their boyfriendsgoing down on them if their hands weren't *ahem properly warmed up.
"Debra, Dave and I had such a wonderful time last night"

"What about your night, I mean we're both on our second honeymoon."
"I started down on him and then he wanted to flip it around so I got on my back and the A/C was on and well, he froze me down there."
"Oh no"
