That's a very NTJ response, YWIR.
I think stereotypical young ESFP behavior is encompassed by "OMGZ!!!11111" I used to work with a woman who I think very much was ESFP and she talked non-stop and people either loved her or wanted to hide from her. She was like the freaking Energizer Bunny on crack. The store manager reprimanded her several times for talking too loud or talking excessively to customers while neglecting her duties. She was really sweet, though, played guitar, and was a really open-minded person. We were friends for a while.
I know some people want to hide under the table when I get emo, but my ESFP mother has a special talent for making absolutely everything a potential episode of Jerry Springer. It scares me sometimes, like, she is totally one of those people who should NEVER EVER talk on a cell phone and drive.
