The birdcage is when a guy has plans to chill with his friends but is then made to feel
guilty to hang out with his woman.
Birdcage can also generally be a
demanding girlfriend.
"Man, you coming out tonight?"
"Yeah, I'll be there..." --- phone rings---- "GOD DAMN
BIRD CAGE!!!!!"
"What's Mike been up to recently?"
"
I dunno, since his wings were
clipped marriage he's really been birdcaged."
