The speaker in the video discusses a Reddit post involving a family conflict regarding a wedding performance. Here is a summary of the situation:

The Conflict: The brother of a bride refuses to perform a song he wrote specifically for his girlfriend of three years at his sister’s wedding.

The Family's Reaction: After the brother played the song for his family as a casual demonstration, his sister insisted that he perform it at her wedding. Despite the brother offering to write a different song for the wedding, the sister and parents pressured him, arguing that it should not be a "big deal" because the person in the song is "just his girlfriend" and not his wife.

The Brother’s Perspective: The brother maintained that the song is personal and intimate, meant specifically for his relationship with his girlfriend. He felt his family’s insistence was an issue of control rather than a desire for a wedding performance.

Public Consensus: The speaker notes that online commenters overwhelmingly support the brother, agreeing that it would be inappropriate to perform a song written for a romantic partner at someone else's wedding.

Humorous Suggestion: One popular suggestion from the comments mentioned by the speaker was for the brother to agree to sing, only to perform "Never Gonna Give You Up" at the wedding to mock the situation.
