Popular examples of best friend symbols include two crossed arrows, interlocking hearts, or infinity and yin and yang symbols. However, if you’re getting a tattoo to symbolize your friendship with your besty, it should represent your relationship. Choosing something that means a lot to you both or represents a part of your journey together can be much more powerful than something generic. Matching images are great, as are two-part items, such as a sun and moon or a lock and key.
