Codeword for 90% attention-seeking, 10% attention-giving. A 90 10 is someone who goes out of their way to get the attention of their peers, much like a pick me. They tend to be egotistical, overdramatic, and above all, fake.

A 90 10 can also falsely create attention around one of their quieter peers in order to try and guide attention back to themself, or alternatively poke fun at a bystander for extra draw.
