Highlighter Kids 

Usually young boys aged 6-11, who wear neon athletic clothing on a regular basis. The term "highlighter" developed because the eye-melting color of the clothing. Generally highlighter kids will be somewhat bratty and annoying, although this may be due to age. If a person above the age of 12 (or even 10) wore the clothing distinctive of this title for purposes other than exercising, they might want to rethink their fashion choices. If you or a loved one suffer from highlighter kid status, do not hesitate to give them a sincere chat.

Miranda: Why do those kids think wearing that stuff is cool? I mean come on.
Helen: *scoff* They're such highlighter kids.
