The word combo of dick and pickle.
Could refer to;
a pickle shaped like a dick
a dick that has been pickled (unlikely)
a person who you want to call a dick pickle
Originated at a restaurant when the cook intentionally served my table a platter with a pickle shaved like a dick.
"Eat a dickle."
"I don't want to eat that, it looks like a dickle."
"Shut up sloot, you love the dickle."
