obsolete To go on or indulge in a wild outburst, spree, or rampage. (Used largely in relation to sports, especially baseball, where the phrase originated in reference to players running amok and ruining the game.) Primarily heard in US. Another fight has broken out between the two teams. These boys are positively tearing up the pea patch! A few rowdy types entered the bar and tore up the pea patch. They didn't even pay for anything!

A minor annoyance. I try to be patient, but I find waiting in line to be such a pea in the shoe. A: "Can you please tell the neighbors to stay off our lawn?" B: "Oh come on, that's just a pea in the shoe. Let it go."

To be very similar, typically in interests, dispositions, or beliefs. Those kids have the same wacky sense of humor—they're truly like two peas in a pod. They're like two peas in a pod, of course they're married!

Said of two people who are very similar in interests, actions, or appearance. Betty and Jennifer are as alike as two peas in a pod, so it's no wonder people sometimes mistake them for sisters.

Especially easy or intuitive. I was worried that the chemistry class would be too hard, but it was like shelling peas in the end.

Particularly stupid, foolish, or narrow-minded. The town hall meeting was hijacked by a few pea-brained morons trying to protest the new highway development. Don't let Tom's comments get you down—he's just a pea-brained jerk who puts other people down to make himself feel smart.

dated A euphemism for particularly thick fog or smog. Originally used to refer to the thick, brown, sometimes lethal fog caused by air pollution in London during the 19th and early 20th century, humorously likened to the thick soup made from split peas. For many older citizens living London during that time, they could as easily be killed by a pea souper as by an attack from a criminal. Heathrow had to suspend all outgoing flights for nearly two hours on Sunday due to a particularly bad pea souper hanging over the city.
