The sadness one feels after a breakup. Usually felt by but not limited to one of the partners (often the partner who has been broken up with). Characterized by crying; blaming oneself; feeling rejected; either losing one's appetite or eating everything in sight; shooting angry glances at happy couples; and cursing at anything related to love including movies, pictures, quotes, and wall posts.
Although these are typically unisex characteristics of the breakup blues, there are some gender-specific characteristics, including eating lots of chocolate (female), refusing to leave the house (female), comments about becoming a cat lady and/or never finding love again (female), listening to lots of Taylor Swift (female), and drinking alone (male). Males function normally when sad.
Girl 1: "Do you think Taylor Swift listens to her own songs after a breakup?"
Girl 2: "Probably. I heard that after Joe Jonas broke up with her, she didn't wash her hair for a week and bought a kitten as well as a sweater with cats on it."
Girl 1: "Poor thing. She had the breakup blues. When my roommate and her boyfriend broke up, she cried in her car every morning and yelled at a Jason Mraz song."
