The act of shitting on a girls mouth, then shaping it into a beak on each lip with your penis, and then spread your nutsack across her face (like wings). then possibly resting your testicles in the girls mouth while stretching your scrotal skin, tell her to scream, lift up your sack and put it in quickly so it sounds like a bird cawing.

Get the birdsmug. Refers to a woman's chest, tits, or breasts size. The word is rarely used in front of women but replaced with a cooing sound.

Get the birdsmug. A manipulation by a penis puppeteer of the cock and balls made by wrapping the hand behind the base of them both, forcing them to stand out together like a bird puffing out its chest.

Get the birdmug. Someone who 'chirps' a lot, much like a Bird. Someone who constantly talks a lot of shit and doesnt do anything to back it up.
