An abbreviation for Long Ass Dick.
You see, your girlfriend knows I got the L.A.D.
Often a person with a name beginning with the letter "D" that that is so anal about the law that he would close his eyes so that not to even look at someone that was merely thinking about jaywalking, therefore earning the name L.A.D. example: Law Abiding Dale
He won't even drive through a yellow light, he is such a L.A.D.
When you have been away from a certain person with an A name for too long (lack of A disorder)
I have been suffering from L.A.D lately.
