"She gave the dungeon keys to bloobertifoo... that weird kid with the long hair and no shoes."
The one girl in your group of friends who never "gets any". Therefore, she has to be the biggest cock block ever. She will bitch about her own life nonstop because it is her only way of getting attention. Also known as "The Blob" or "Slobrey".
