What does "helluva" stand for?
Here's an extract from The catcher in the rye;
"Stradlater's all right He's not too bad," I said. "You don't
know him, thats the trouble." "I still say he's a sonuvabitch. He's a
conceited sonuvabitch." "He's conceited, but he's very generous in some
things. He really is," I said. "Look. Suppose, for instance, Stradlater was
wearing a tie or something that you liked. Say he had a tie on that you
liked a helluva lot--I'm just giving you an example, now. You know what he'd
do? He'd probably take it off and give it ta you. He really would. Or--you
know what he'd do? He'd leave it on your bed or something.
