Meaning of "All in My Head (Flex)" by Fifth Harmony

The lyrics of "All in My Head (Flex)" convey a longing for a romantic and intimate connection with someone. The repeated phrase "Flex, time to impress" suggests a desire to showcase oneself and impress the other person. The singer wants this person to come and climb into their bed, indicating a desire for physical intimacy. They encourage the other person not to be shy and to do their thing. However, as stated in the line "It's all in my head," it becomes evident that the entire scenario is a product of the singer's imagination.

The next verse introduces the image of curtains closing in like waves, creating an intimate and private space for the singer and the other person. The dimming of the lights symbolizes a desire to create a more sensual and intimate ambiance. The mention of laying on roses implies a sense of luxury and romance. Despite these seemingly romantic and intimate elements, the singer acknowledges that it is all happening in their head.

The repetition of the line "I wanna feel you under my body" further emphasizes the yearning for physical closeness and intimacy. However, it is emphasized that these desires can only be fulfilled in the singer's imagination. The phrase "Flex, time to impress" continues to drive home the idea of wanting to show off and impress the other person, but it remains an unattainable fantasy.

In the bridge, the lyrics introduce Zoo, possibly referring to rapper Fetty Wap's alias, who expresses the same desire to "flex" with the other person. This section adds a sense of confidence and assertiveness to the lyrics, as Zoo declares that they can't be flexed on. The mention of spending large amounts of money suggests a display of wealth and indulgence, further underscoring the desire for extravagance and impressing the other person.

Ultimately, "All in My Head (Flex)" portrays a scenario of longing and desire for a romantic and intimate connection, but it highlights that it is all fantasy and exists solely within the singer's imagination.
