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."
LTB is an acronym for "low trafficbathroom". This is usually used in reference to bathrooms in public places, such as airports or convention centers.
LTB's are a desirous commodity, in that they provide one with a stench free place for defication, contemplation, urination, and mediation.
All the stalls in the first floor bathroom are full, and there are hobos performing handjobs in the second floor bathroom. The bathroom behind the kitchen next to the janitor's closet on the fifth floor is an LTB.
