blonkers means: This is a form of eyewear. Blonkers, which are similar to blinders but completely invisible, are often worn by car lovers who have a particular model or manufacturer. It’s not always easy to identify a blonker until they start telling you the weight of their car, its power to weight ratio and other details. If they inform you of the difficulty in tuning an NA engine properly, it would be a dead giveaway. (in Community Dictionary, added by Valeria Hart)
