(chěs'tāsh', chə-stāsh') -noun.
Chest hair on men, which is allowed to grow without shaving at the top of
the chest (in any of various shapes), and shaved clean from well above the nipples down to the waistline.
A chestache allows a manly
appearance in a partially unbuttoned shirt, but with a cleaner
appearance below the chest whilst shirtless.
"I like his chestache, but it sure gives him a weird
tan line."
"I love running my fingers through his chestache."
"His
handlebar chestache is oddly appealing, but
I wonder how much wax it takes to do that"
