bird-poo-encrusted

adj. Frosted with a just-in-time-for-summer coating of doo doo--courtesy of a fine, feathered, fecal friend.

Real citation: "I also scrubbed down the black metal table and chairs that Ken's mom gave us for the back porch, so now they're useable, rather than being bird-poo-encrusted. I keep telling myself I'll sit out there with the laptop and work, and now I have no excuse. Unless it gets really hot or rains."

Made-up citation: “In some cultures, having a bird-poo-encrusted head is considered good luck. To the rest of us, it’s just ishy, gross, dirty, wrong, and it sucks.”
