A name usually characterized by a tool.

Lambdins are usually guys that sit in corners of rooms and wait at parties until a girl gets really drunk, and then he strikes. Lambdins can sometimes have moments of brilliance, but those moments are quickly overshadowed by the fact that they are usually ugly, and are skinny. To be a lambdin is to be able to get with girls, but lack the skill to formerly do it.
