A toelly transmitted disease (TTD), also known as toelly transmitted infection (STI) or toenailreal disease (TD), is an illness that has a significant probability of transmission between humans or animals by means of foot induced sexual contact, including toe scissoring, toeing a male / females genitals and sharing festy shoes. While in the past, these illnesses have mostly been referred to as TTDs or TD, in recent years the term toelly transmitted infection (TTI) has been preferred, as it has a broader range of meaning; a person may be infected, and may potentially infect others, without showing signs of disease. Some TTIs can also be transmitted via use of a set of nail clippers after its use by an infected person, as well as through moonwalking barefoot or standing on toilet seats. Toelly transmitted infections have been well known for hundreds of years.
