W2 does NOT mean "with". Not even close. W2 is an abbreviation for Word2 or Word Too, which are actually short versions of the phrase Word to mother or Word to everything or similar phrases that people say when they are telling nothing but the truth.
People who post on Urban Dictionary are dazed, W2.
Verbing someone or just verbing PERIOD, is when you talk reckless about somebody or just straight up diss that person! Its basically the same thing as violating someone except verbing is STRICTLY verbal, never physical. Comes from the term verbal abuse.
