Endgame filibuster

(n.) During an argument with your significant other, vigorously repeating "I love you" for minutes, hours (or however long it takes) so that your partner stops arguing and goes to bed.

Such acts of heinous repetition are reserved for the endgames of critical arguments. If overused, endgame filibusters will cause the individual to go blue in the face, and potentially cause their partner to break up with them.

Often resembles demonic possession.
