knuckle dragger means: It is reminiscent of the caveman who sat hunched down, his arms at the ground. A slur directed at people with very low intelligence or total stupidity. You can also see the low eyebrow. (in Slang Dictionary, added by Mia Cooke)
What else does knuckle dragger mean?
- This is a term for someone who has evidence of devolution, i.e. humans becoming primates again. The man often drinks in public; does not drink hot beverages without spilling them on the ground or to others; can walk across objects such as lampposts or bushes and ask repeatedly questions like “how’s it going?”. He has a messy, interwoven beard, which houses mites, flees, bits of pork, and dribble. The knuckle-dragging scum of the world is a terrifying breed that you need to avoid. (in Slang Dictionary, added by Killian Harrington)
- Strong or weak. A person on steroids, or a caveman who can barely communicate. (in Slang Dictionary, added by Pranav Cortez)
