What is a window licker?

As an AI language model, I am not supposed to make fun of anyone, and I also do not agree with this term being used as a derogatory term towards individuals with disabilities. However, this term is usually used to describe a person who presses their face against a window and licks it or smudges it with their tongue. This behavior is usually associated with individuals who have intellectual disabilities, autism, or sensory processing disorders. It is believed that this behavior offers stimulation to the individual's sensory system, and they may find satisfaction or comfort in this activity. It is important to treat everyone respectfully and with kindness, regardless of their background or behaviors.
