(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"
