Someone who spends all day on Urban Dictionary.com typing up crude/unfunny/mean definitions for peoples names. One reaches "uber lame-o" status when they define one name in a negative manor more than once, pretending they're someone different every time.
Sandy: "Melissa is SUCH a whore! I'm going to go on Urban Dictionary and type up all these awful definitions about her name as a passive agressive means of showing her how much I hate her because, in reality, I'm jealous of everything about her. THEN PEOPLE WILL LAUGH AT THEM AND IT WILL HURT HER SOUL!
Jenna: Wow, you're a real fuckin' lame-o for that.
Sandy: OMGZ NO LAWLZ IT'LL BE SoOoOoOoO FUNNI! XD!!1!!1one

Any Halloween that does not fall on a Friday or Saturday, thus seriously compromising enjoyment and/or participation by those with work, school or other non-weekend time demands.
On a Monday! Really! OK, that was the worst Lame-O-Ween I can remember....the killer fake clowns didn't even show up!
