Noun: something that a person does to bring on humiliation, embarrassment and social awkwardness. This action or communication usually causes others around to laugh at that person.
Pablo: Take a shot of this.

John: (takes the shot, slams shot glass on the table). WOOOO!

Jennifer: (laughing at John's awkward exclamation). That was the nightbreaker!

John is now embarrassed.
