Noun. A description a person who is perceived to be an extremely faggy little bitch who is a pathological liar and jackhole. The individual in question is extremely annoying, petty, spiteful, and prone to wild emotional swings and yet is tolerated by his peers because a member of his immediate family (most often his mom) has no self respect and as such is a complete whore like Cartman's mom.
A Zither's social status is tenous and dependent upon (1) the extent to which people can laugh at how awful his life is, (2) the quality of gifts married men bring his mom, and (3) how humerous his self hatred is.
Why are we hanging out with this piece of shit?
He's a total Zithers and my balls are blue as hell.
Sweet, once that married dude busts his nut we'll get our dicks wet!
