JACKSON: So, I hear the huckleberry crops are gonna totally suck this year!
[Sookie just looks at him.]
Huckleberry is an American dialect word for the shrub fruit known as the bilberry – a variant of the English dialect word hurtleberry or whortleberry. In America, the term huckleberry is applied to several different species of berry, including dangleberries and blueberries.
The peak season for huckleberries finishes in mid-September, so by this time of year the huckleberry crop would normally “suck” anyway. No wonder Sookie gives Jackson a look.
The huckleberry crops serve as a reminder of Huckleberry Finn.
