How to sign “Fast” in ASL
The BSL sign for “Fast” isn't in our dictionary yet — it will be fingerspelled in BSL mode, never replaced with this ASL sign.
Step by step
- Shape both hands into L handshapes, with your thumbs resting between your index and middle fingers.
- Wrap each index finger around the outside edge of its thumb, keeping both hands in front of your chest.
- Snap both thumbs upward and back in one quick motion, landing in modified X handshapes.
- Make the snap small and sharp, ending with the thumbs raised slightly rather than wide.
- Keep your palms facing each other through the motion and your elbows relaxed at your sides.
- Pair the sign with an energetic expression, making it bigger and sharper to mean even faster.
Practice tip
Think of flicking something off your fingertips — that snap of the thumbs is the whole sign.
