L.D. 

L.D. Has an amazing personality. He knows how to have a good laugh and have a good time. He's always there to cheer you up when you feel blue. He cusses a bunch and even talks dirty sometimes, but he's super cool. And the one thing he will never do is let down his girl. He always lets her know he loves her and wouldn't do anything to hurt that.

Girl 1: That guy is such a L.D.
Girl 2: I know! I wish he liked me though!

L&D 

Liquor and Drugs

Biff wasn't feeling so hot after a 2 day bender with his lover, Sally Sue. He started to feel a little like a shell of himself, seeing shadow figures jumping around in the corners of his plane of sight. He figured it might be time to pack it in for a while and recoup. Alas! Lucky for him, he was hanging out with his friend Dick York who is hailed as the King of L&D! Lil Dicki told Biff that "Sleeping is for chumps! You can sleep when you're dead!" So, Biff ripped a few lines, slugged a few shots, and went back for round 3 of the bender and with his dank skank mami, Sally Sue, who was in the bedroom ass up ready to rumble again! Praise Be to the king of L&D!
