Describing people who are ready to do anything for popularity can be complex, as motivations and behaviors vary. Here are some ways to describe them:

• Attention-seeking: This describes someone who craves attention and will go to great lengths to get it. Cambridge Dictionary
• Fame-hungry: This describes someone who desires fame and is willing to do almost anything to achieve it.
• Approval-seeking: This describes someone who constantly seeks validation and approval from others.
• Opportunistic: They might exploit situations or people to elevate their status.

• Narcissistic traits: Individuals with narcissistic tendencies may seek popularity to validate their inflated sense of self-importance. Mayo Clinic
• Low self-esteem: Sometimes, the pursuit of popularity stems from deep-seated insecurity and a need for external validation.

• Superficial
• Insincere
• Manipulative
• Desperate
• Calculating

It is important to consider context and individual motivations when describing such behavior. Not everyone who desires popularity is inherently negative; some may simply be driven by a desire for social connection or a sense of belonging.
