-A dumb person whose defining feature is luck.
-A fat fucktard, who is dumb (which however has nothing at all to do with the name).
-A subpar dude, no doubt about it, engaged inthe process of having luck.
-Look at that fat lucktard being all fat and lucky (and dumb, but not that dumb).
-Look at that lucktard, who is so dumb, and a little fat, I guess, but mainly just lucky (and dumb; gods, I hate him).
-Look at that lucktard, being all subpar and all (but otherwise fine, I guess?).
A fucktard that often uses their mouth, tongue, or other associated body parts to inspect or learn about objects and materials that are very clearly hazardous.
Similar in nature to a creeptard. A lurktard is an individual prone to creepily making passes at another individual, usually of the female persuasion. One may most often find a lurktard creeping in the darkest shadows of bars and sketchy college parties. A lurktard often doesn't respond well to rejection. In lieu of retreating with intention to move on from their rejector, a lurktard will retreat with intention to incessantly facebook/myspace stalk their victim.
"Did you see that guy pretending to get PJ last night, even though he didn't want any, just so he could talk to me? What a lurktard!"
