Celebratory sex, similar to giving a "High 5," a low one is meant to congratulate someone for an achievment with sexual favors.

An act which fuses the raw power of the pelvic thrust with universal symbolism of the high five. In effect, two males, usually Bros will pelvic thrust at one another, making their shafts collide in a meaty power-clap. It should be noted that as balls are not touching, the Low One is acceptably straight.
