The art of being exceptionally twat-like. Usually this role is filled by someone who is unaware of their obnoxious, clingy, and overall bitchy attitude and personality. Such girls are commonly running late to work/school, browsing forever 21, wearing leggings in the dead of winter, and dancing on tables to Lady Gaga.
Jenna's twaty attitude was getting on my nerves!
Anne is is being really twaty, so i am going to punch her in the face.
