A vertical strip of hair on a man's chin, similar to a "flavor saver" but generally lower down on the chin. The name comes from the latin root "butt" referring to the tickling sensation on a woman's anus from the hair while the man eats out her pussy.
My friend stated that his girlfriend loves his butt tickler and his improved their sex lives astronomically.
