Tic refers to a sudden, repetitive involuntary movement or sound that someone makes without realizing it. It's used to describe a nervous habit or twitch. For example, constantly blinking, sniffing, or clearing one's throat can be considered tics. The word is often used in the medical field to describe a disorder called Tourette's Syndrome, which is associated with involuntary tics. In everyday language, we might use the term "nervous tic" to describe someone's fidgeting or twitching when they are feeling uncomfortable or anxious.
