WTG

"WTG" is an acronym that stands for "with the grain." It refers to a shaving pass in which one shaves in the same direction that the hair grows. A WTG pass can be compared with a pass that is XTG ("across the grain" or direction of hair growth) or ATG ("against the grain" or direction of hair growth).

Different kinds of passes are commonly combined into a single shave (see The Multiple Pass Shaving Technique).

Another commonly-used three-character acronym is BBS ("baby's bottom smooth").
