A child ranging from ages 5 through 10 with a Kool-aid mustache usually red from the cherry flavor, they pass time by digging in the dirt with forks, spoons, and the occasional knife, extremely unsupervised by parentals.
That fucking kid down the street stole my kids bike that dirt digging Kool-aid face!
A red ring of bloody menses on a lover's face, after oral sex with a menstruating woman in the dark. Usually the result of not having the lights on, although some actually enjoy it.
Wake up... that was so *good*... Oh my God, you've got Kool-Aid face! My period must have started last night!
What? You mean I've earned my Red Wings?
