The Big Chill Bird Switch
The phase was coined to describe a maneuver in which, at flat party or night oot, one chats intensely to a sole female for 1 to 2 hours without distraction. When the time limit expires for chat, one immediately leaves the first female and moves to another, sole, female to repeat this.
The following example is a joke. Let it go. Or be triggered forever, RIP.

"Oh he did the Big Chill Bird Switch last night, it was amazing. Still never pulled though."
