Get the classturbation mug.
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.
"why does she keep talking about how she's the classy one in this feud"

"she's just classturbating. she's a chronic classturbator".
