The coolest type of bird EVER. They carry messages on their feet because they're so cool. They're basically n00bs that do stuff for you. A great example is Shap. Except for the fact that Shap isn't really really cool.

A Carrier Pigeon is a cheating girlfriend who has two or more boyfriends that she gives oral sex to on a regular basis, even only hours apart, thus kissing each boyfriend with a smattering of jizz in her mouth from another boyfriend.
JP was pleasantly surprised to find Brooke had been playing carrier pigeon when, during a kiss, she spat a creamy load of Ryan's jizz into his mouth.
