n. An undesirable renter, who flies in, shits all over everything, and flies out, leaving the owner and neighbors to clean up their mess.

Get the shitbird mug.
Any creature whose only purpose seems to be indiscriminately shitting on everything. Just eating and shitting, this creature serves no purpose other than to breed more shitbirds who will eat out your substance and shit on you in thanks.

Unless the shitbird has attained human rights protection - Destroy on sight. As well, build shitbird-proof barriers around yourself and avoid flocks of shitbirds. Good day!
