Fruity and Nutty

Listen up, buttercup. This joke is so simple, even a bear like me can understand it. The person is sayin' they're like a fruitcake 'cause they're "fruity" (code for maybe bein' into the same sex) and "nutty" (aka crazy). You probably thought fruitcakes were just somethin' your grandma makes with questionable ingredients. Well, surprise! There's more to it, genius.
