You stick your poles inside me. You tie me down to get me up. I get wet before you do. What am I?

One answer for you, from port one and two. Total Occupation Swish Boss Fish Job Butterfly Company Crow ten, play it backwards.

Across and down my clues are pressed; Small squares wait while minds are tested. Words all meet where letters are shared.

I’m why this post exists tonight. Keep me up or watch me die. A mean one’s looking for a fight, A bright one tears across the sky.

I hide in strings and wooden keys, I flutter out on laughing breeze. I make your shoulders sway and swing, without a single visible thing.
