"True Blue" by Boygenius is a song about the comfort and reliability of a deep friendship. The song is a tribute to a friend who has seen the singer through various struggles and helped them find their sense of self. The opening lines describe a day at the beach with a friend who was born in July '95, emphasizing their youth and vibrancy. The friend is described as having 'summer in their blood,' which speaks to their warmth and lively nature.

Later in the song, the lyrics reveal that the friend moved away to Chicago and went through some difficult times of uncertainty and self-discovery. Despite the distance, the friendship remained a constant source of support and solace, as evidenced by a phone call when the friend was on the train and feeling low.

The song also acknowledges that the friendship isn't perfect, as the friend has "hurt [the singer's] feelings three times", but ultimately it's a source of great comfort and strength. The chorus repeats the phrase "It feels good to be known so well/ I can't hide from you like I hide from myself" which highlights the trust and familiarity that comes with a deep relationship. The last line of the song, "your love is tough, your love is tried and true blue" is a heartfelt expression of gratitude for the friend's unwavering loyalty and love.
