This happens when your body knows when you are getting close to home and automatically wants to expell all feces in short order

When you know you need to do a “big job“ but you’re miles from home.

You know you can make it to your own bathroom, but as you close in on the last half mile the urgency increases. Ass Radar kicks in and knows you’re almost there.
Yeah, I almost crapped my car the other day. Ass Radar kicked in and overrode my will to reach the bathroom.

An uncanny sense of just whose ass you need to kiss to get ahead.
As I watched from across the room her ears perked, her eyes scouting the room while her head bobbed like a bleep on a screen....her ass radar was telling her just where she needed to plant her lips.
