The Austrian Cheese Bath is a sneaky, lewd act pulled by room mates and general douche-bags.
One will remove the cap from another's body wash container, and ejaculate inside of it, where it shall lay unnoticed until the unsuspecting victim showers next.
If placed inside a shampoo bottle, (head and shoulders works best) it is known as Austrian Hair Gel
A particularly hairy man may experience yogurt flakes
when engaging in an Austrian Cheese Bath.
