U-Twit 

Someone who keeps submitting the same definition repeatedly to Urban Dictionary hoping to get published. Often a personal slam on someone they do not like, or a disgusting made-up sex act. Illiterate U-Twits, or IUTs, cannot even spell most of the words correctly when they bag on someone or make up a violent sexual act.

Jeff is such a U-Twit, he keeps posting on Urban Dictionary that Jane Smith is a totally skanky ho from who has gotten a (insert gross sex act) from every guy in school.
