The term 'go furtively' can be defined as to move in a stealthy or secretive manner. This can be accomplished by using words such as SLINK, SNEAK, SIDLE, and SKULK. Slinking is the act of moving slowly and gracefully with a smooth, sinuous motion. Sneaking is the act of moving quietly and cautiously, often in order to avoid being noticed. Sidling is the act of moving sideways or obliquely, often in a cautious or sly manner. Lastly, skulking is the act of moving stealthily or furtively, often with the intention of avoiding detection. All of these words describe the same action of going furtively.
