I'm a Birdy
A way to brag about being totally wasted, usually because you took too much of something stupid and now you're floating around like a drunk flamingo.
"I'm a Birdy, I just ate a whole bag of candy and now I'm flying in circles."
"I'm a Birdy, I just took a hit off a bong and I'm seeing monkeys on the ceiling."
"I'm a Birdy, I'm so high I think my pants are made of clouds."
