a large 8 inch man. Who stiffens up when agitated/excited. Some people refer to it as a penile organ. But sophisticated people refer to their dong as a Lumar. The L must be capitalized since it is a proper noun. Treat your Lumar with care, for it has feelings too.
Amanuel: Hey did you see Hannah's Lumar?

Prabh: Yeah, I think he was trying to talk to me!

Lumar: I'm a penis!
