A small clueless child (in grade seven) that creepy grade nines "pounce on". Often, this relationship ends when the grade nine meets the childs friends, or when the child figures out the "niner" is perverted.
"Do you know a kid named Tony, in grade nine?"
"Isn't he the creepy one?"
"Yeah, well he's dating a grade seven!"
"That poor, Sevy"
