the incessant referral to how classy one is. masturbating your own ego about being a really classy person. verbally jacking yourself off because everyone else probably thinks you're a real horse's ass. read: the opposite of classy or having class.

When you sit in class and caress you dick until you ejaculate all inside your school pants. You are addicted to masturbating and you can't go a class period without jacking off. You usually don't realize that everyone is watching you and making fun of your addiction
