Tongue Splitting
Tongue Splitting is the central bifurcation of the lingual frenulum. This gives the visual effect of a "forked tongue" and instills more broad ranges of movement and the ability to control each side of the tongue independantly. Some people are naturally able to do many things with their split tongue, others have to work at it.
