A phrase used out of anger, usually in place of "son of a bitch." As it contains no curse words, it's okay to say in public.
Teacher: So don't forget class, your essays are due tomorrow.

Student: Son of a dick! I totally forgot about that.

Teacher: Excuse me! What did you say?

Student: It's okay, I didn't say son of a bitch, I said son of a dick. That's clean.

Teacher: Oh, I see. Never mind.
