Top definition
A derogatory term for a female who engages in oral sex, or more commonly known as giving dome, all the time. She is proud of her status as an object whose sole purpose is sucking. Use the term wisely.
"Hey, Leah, give head to more guys...you suction device!"
"Shutup. I'm gonna go cry now." She then proceeds to do what suction devices do best to cheer herself up.
