I'm just here to shit my pants - You're so uninterested in looking cool that you're just here

You're so uninterested in looking cool that you're just here to poop your pants and not care.

I’m not here to look good. I’m here to shit my pants and eat a sandwich.

I came to the meeting just to shit my pants and ignore everyone.

I didn’t come to this party to be cool. I came to shit my pants and be weird.
