A Kar Leng is someone who drags down someone else be it physically or mentally. Usually making someone late for a meeting and/or dragging someone down with her.
For example, "Can you stop dragging me down John, you are being such a Kar Leng." or "Can you stop spacing out? Your being such a Kar Leng right now!"
