To receive fellatio whilst pretending to be a dinosaur. The most popular method is to flap your wings while shrieking like a pterodactyl. Another common method is to roar while waving about your short T-rex arms.
"Dude, I hear she gave you dino-dome!"
"Yeah man, I flapped my wings and was all like 'ka-caw, ka-caw!'"
