I think of chirping as specifically mean-spirited bullying, especially in an attempt to provoke a reaction. Source: grew up in BC.

For chirping, I'll bring up Shoresy, spin off of Letterkenny TV show, https://en.wikipedia.org/wiki/Shoresy

The film Slapshot with hockey banter/ribbing (at a Gilmore Girls-type pace).

Having courtside seats at a basketball game means getting to listen to the players chirp each other.

It might be more popular in Canada but I think "chirping" is pretty common in the US.

yeah heard it a bunch in the context of talking shit in sports

I remember being very amused at a party when hockey, baseball and football players were teaching each other their respective lockerroom slang.

Nah if you say someone chirped you say, on the street or in a pub, it's fighting words...

I've always took it as the opposite. Chriping is just noise with no real threat (most chirping birds are not a threat to humans). It's just someone being friendly with their banter usually in a making fun of you type context.

Maybe it's regional but definitely was fighting words when I grew up in Alberta. If you were bantering with your friends we'd just call it "bullshitting", "talking shit", etc...

"Fuck you, Shoresy!"

I'm not into sports so I don't really know that angle but I did have a roommate in Ottawa who got into a fight outside of a bar because "some guys were chirping" him.
