A ballflarp is a male version of a qweef. Gas that excretes a males buttocks and creeps up between the testicles and the thigh creating a thunderous clapping.
Wow I atetoo much bean dip and my skinny jeans are so tight . I'm so gonna ballflarp tonight.
A training technique in golf. If a person's head comes up too much during their swing and it is adversely affecting their shot, a clamp can be hung around their neck and attatched to their groin so they will have incentive not to pull their head up during a shot.
"I kept slicing all my teeshots to the right, so my trainer made me wear a ball clamp all game!"
