This is a rare thing, but it can happen. A cool sevie is a seventh grader who has maraculasly gained the approvial of any of the "cool eigth graders." :)
Jenna(7th grader)(to eigth graders): Hey guys!
Multiple 8th graders: Hey, it's the cool sevie!
Kayla (7th grader) (to 8th graders): Hey!
Multiple 8th graders: Why is she talking to us...?

(It can be more than just 8th graders, too.. it can be any 8th grader or high schooler.)
