1. Derives from the fusion of the two words "liquid" and "turd;" excrement that expels from the anus not in the usual solid form but as a continuous, sometimes lighting-quick, fluid, filling the toilet bowl or possibly coating the rim of the toilet bowl as if being shot from a paint cannon.
2. A contemptible person, whose guts and blood you would like to see splatter from his or her body like "liquid terd" from an anus.
3. In hick speak, a "loud kid" or someone who does not know how to be quiet or subtle with any normal day-to-day activity, such as eating, moving a table, talking on the phone, or putting away dishes.
"I just spilled a bigtime lurd in that toilet that it rocketed out of my butthole, and my buttcheeks were coated with its spray."
"I can't believe he would rat me out like that, I could just kill that lurd."
"Can he do anything without making such a racket?" "No, cause he's a lurd."
An extremely good friend but thrives to be the best. Naturally good at games immediately after learning the controls. You wouldn't want to piss him off by hurting his friends or family because if you do, he'll make sure you suffer.
Woah, Lurd is so good at that game! He only started 3 days ago!
