"That Guy" by Astrid S explores the topic of a self-centered and egotistical person who dominates conversations and lacks genuine interest in others. The lyrics depict the singer's frustration with this type of individual and her realization that they are not worth her time or attention.

In the first verse, the singer expresses her preference for individuals who remember her name, indicating a desire for genuine connections. She also points out that the person she is referring to seeks attention by eliciting reactions and considers anything mainstream as unappealing.

The pre-chorus introduces the idea that this person tries to portray a lavish lifestyle they cannot afford. They used to idolize Los Angeles but have lost interest. The singer's attempts to engage in conversation are constantly ignored, which leads to her frustration.

The chorus highlights the singer's realization of the person's true nature. Using the phrase "oh shit," she acknowledges her recognition of that guy, referencing his tendency to talk incessantly about himself. She questions whether he truly believes he is worth her time and acknowledges that she is aware of his type.

Moving into the second verse, the singer implies that the person's self-centeredness might stem from a lack of attention during their upbringing. She suggests that their need for attention may stem from insecurities, referencing the size of something (presumably their ego) and the absence of drawings on their walls.

The bridge adds another layer to the narrative. It starts with the person contradicting themselves, claiming they don't want to hurt the singer. The singer responds by sarcastically saying she's not like "other girls," implying that she sees through their insincere words. The repetition of "oh shit" emphasizes the singer's realization and growing frustration.

The final chorus reaffirms the singer's awareness of that guy's self-obsession. While he may not realize it, she sees through his facade. The phrase "Who you tryna be?" suggests that he is trying to portray a certain image or persona, but the singer is not fooled. She reiterates her understanding of his type and once again expresses her exasperation.

Overall, "That Guy" delves into the theme of self-centeredness and the frustration it can cause in interpersonal relationships. Astrid S presents a strong and assertive perspective, asserting that she will not tolerate individuals who only talk about themselves and fail to show genuine interest in others.
