Anyone familiar with esoteric symbolism knows the triangle is a phallic symbol(1).  He's adding his tongue to it.  What could that mean?

1. "The upward moving triangle is sometimes called the blade (the chalice and blade figure ceremonially in many ritual magic operations). It is a symbol of aspiration or rising up, male force, and fire. It is purely phallic in origin. The triangle represents aspiration, rising force, and the male principal.
