Grits is (are?) vile, flavourless, lumpy porridge-like substance.
However, if you come to me hungry, you know I'm going to fill you full of grits. If it's loving you're after I'll kiss you and give you the shivering fits.
If grits is something to do with gristly penises, perhaps hunger and loving could be dealt with in one go?
Ahem.
Fiddle-dee-dee.
Penis.
