there is no widely-known Glasgow gang known as "The Tongs." It's possible that new gangs or groups may have emerged or adopted this name , but I don't have access to real-time information.
In general, the names of gangs often have historical, cultural, or local significance. Sometimes, they might be derived from the area they operate in, specific symbols or terms associated with their activities, or even names chosen to instill fear or respect in their rivals.
If "The Tongs" have gained prominence or notoriety , I recommend conducting a search using up-to-date sources to learn more about their origin and history. However, please keep in mind that discussing criminal activities or promoting violence is not appropriate, and my purpose is to provide information in a responsible and safe manner.
