To dip; to use chewing tobacco, also used as a noun to mean dip. commonly used to discretely suggest to another that the two should go to dip in the bathroom. The phrase "Slay all dayyyyy" is used by non dippers to ridicule the dippers because at one time the phrase was quite common in the dipping community and taken seriously. The word is still in use although a few teachers and administrators in the area have discovered the meaning rendering the term un-usable in their presence.
