Get the Rackedmug. Rack (verb): To strike a male in the groin, specifically in the testicles. Despite the highly painful results, the term 'rack' generally expresses playful, friendly, or prankish intentions. Though its origins are unknown, it is suspected to have grown from the common billiards term, to rack ("rack up") the balls for the striker.
"Jon stole my last soda, but I racked him, so it all evened out."
"The golf ball ricocheted off the tree and racked Frank, causing him to keel over in the midst of his laughing friends."
