Lift the balls. When you ask your significant other to lift your ball sack from your taint. This allows you to air out your balls with a cool fresh breeze of air. Typically, LTB is performed while you are laying down on your back.
Just came home from a long day at work, laid down on the bed and told my girl, "LTB."
When my balls get sticky or sweaty, I just say the three letters, "LTB."
