Definition: A stimulant compound or drug found in coffee, tea, and soft drinks.
C hand shape for 'drink/beverage' then 'eyes-wide open!' -- two C hand shapes move up (palms face each other) held at eye-level (with two 'big eyes' between them).
Lyn Wiley comments: "My most favorite fun-sign is caffeine signed this way. I think of the translation as: ingest caffeine, eyes, mind and body revved up and on-high-alert! The hand shapes, movement and location -- all of those are simple for fist-time signers. And if the student does not drink coffee it's a certainty that they know someone who does. So the sign always, without exception, prompts classroom laughter (and I love that).
