Body Language Doctor. A BLD is a person who has a fantastic amount of success in studying the probability of two people fucking based on their body language. BLDs are born to help. They are selfless and often find themselves neglecting their own love lives in order to give direction to the relationship-needy. The common practices of a BLD are similar to that of a free mason; nearby BLDs meet every once in a while to discuss recent hook-ups, break-ups, and fuck-ups within the thirsty community.
