First, sounds like a declaration of agreement, sounds like something that sees; could just be me.

I can make myself known without noise or form. Or if my creator so intends, signal my presence by roar. It's your cue to flee Often laughed at, but I can clear a room in seconds

I have many stamps but no letters to send, A paper trail that has no end. Red tape and long lines. Follow my rules or you’ll run out of time. Common sense and empathy..pssh don't mean jack, Just ask Hermes Conrad, how he lost his groove back.

A weak argument A shaky ladder Prone to fall apart An excuse you don't want to hear

I’m called boring before you even try me, yet I’m in ice cream, vibes, and bedroom slang alike. What am I?
