A sexual maneuver requiring the man pull out on the verge of orgasm, tightly gripping his cock with his hand and holding in the jizz until the orgasm has ended. Once he has calmed down some and being pestered by his lover about why he's standing there holding his cock, he leans his lover's head back, positions the head of his cock inside their mouth and releasing the grip on his penis allowing the jism to dribble out like a pigeon feeding it's young.
Justin: Dude, you remember that bitch I was with last week?
Kevin: Yes, yes I do.
Justin: I gave her some pigeon milk.
JC and Kevin: MNYEH!
