fart-chirps
The farting, chirp-like sounds that are made by parakeets when they talk to one another. May often include clicks or squeaks as well.
Frenchie and Mr. Cheeks always do their little fart-chirps at night; it's funny to listen to while I'm studying or doing my toenails (if this doesn't prove once and for all that I'm FEMALE, I don't know what will!). Plus it's more original than the crap 50 spews out over the radio.
