Phoebe Buffay's theory that lobsters link claws and mate for life.
The person you are supposed to be with the rest of your life.
Phoebe: (in reference to Ross and Rachel) hang in there, it's gonna happen
Ross: Okay, now how do you know that?
Phoebe: Because she's your lobster.. come on your guys, it's a known fact that lobsters fall in love and mate for life. ... you can actually see old lobster couples walking around their tank holding claws
Similar to what commomn folk refer to pubic lice and/or crabs. The difference being the much more massive and intense grasp more prevalent when reffered to as a lobster. Dont want it. It sucks. Ask Tyler!
Fuckin pubic lobsters been camped out in my pubes now for like a month and still aint payed no rent. Motherfuckers!
