'Bilabiate' means having two lip-like parts or lobes. It's often used to describe the structure of certain flowers or the articulation of sounds using both lips. Think of it as a split or divided lip. It is most often used in botany. A bilabiate flower, for example, has petals divided into an upper and lower lip. In speech, sounds like 'p' and 'b' are bilabiate because they require both lips.
